AB  - The B4C-SiC composites were obtained through densification of B4C and β-SiC powders with different ratios using Spark Plasma Sintering (SPS). Thermal treatment was conducted in the 1850–2000 °C temperature range under pressure of 70 MPa. Starting powder ratio effect on sintering behavior, relative density, microstructural development, and mechanical properties of obtained composites was investigated. Results showed that only starting compounds were observed in sintered ceramics with uniformly distributed and densely compacted B4C and SiC grains. Maximal relative density (100 %) was achieved for 25 % B4C-75 % SiC sample densified at 2000 °C. Obtained composites' microhardness ranged from 33 to 43 GPa, depending on constituents' content and densification temperature. Maximal microhardness was achieved for composite with the maximal amount (75 %) of B4C densified at 2000 °C. Composites' behavior in extreme conditions was evaluated through their interactions with laser beam and obtained results showed that SPS is effective densification method for obtainment of additive-free B4C-SiC composites applicable in extreme radiation environments.

AB  - Multicomponent oxide with pyrochlore structure (A2B2O7), containing 7 different A-site cations and 3 B-site cations in equiatomic amounts, was synthesized. Powders with nominal composition (La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 were fabricated through a reaction of metal nitrates (A-site) and metal chlorides (B-site) with sodium hydroxide during the solid state displacement reaction. Room temperature synthesis initially resulted in the obtainment of amorphous powders, which crystallized after subsequent calcination to form single crystalline compounds. Crystalline high-entropy ceramic powders formation took place at temperatures as low as 750 °C. During calcination, defective fluorite (F-A2B2O7) and crystal pyrochlore (Py-A2B2O7) structures coexist. A large number of cations induce the obtainment of stable high-entropy pyrochlores. Results showed that sintering at 1650 °C lead to pure crystalline single-phase pyrochlore formation. High-density ceramic, free of additives, was obtained after powders were compacted and subjected to pressureless sintering at 1650 °C. Multicomponent pyrochlore structure was investigated using the theoretical and experimental multi-methodological approach.

AB  - A novel class of high-entropy pyrochlore compounds with multiple elements at the A and B site positions (A2B2O7) was successfully obtained. Powders with (La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 nominal composition were fabricated from pure metal oxides obtained through a reaction of metal nitrates (for site A) and metal chlorides (for site B) with sodium hydroxide during the solid-state displacement reaction (SSDR). The phase evolution was analyzed using XRD method. During the thermal treatment of ten individual metal oxides, the single pyrochlore phase was created. The present study showed that the highdensity (98%TD) ceramics with a hardness of 8.1GPa was successfully obtained after pressureless sintering at 1650 °C for 4 h. Results of the Raman study and the Rietveld structural refinement showed that sintered highentropy ceramics is characterized by a single-phase pyrochlore structure, which was investigated in detail.

AB  - The goal of this research was to obtain a chemically complex multicomponent
oxide with the A2B2O7 pyrochlore structure with nominal composition
(La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 that contains 10 different
cations in equiatomic amounts which was obtained by reacting metal nitrates (site
A) and metal chlorides (site B) with glycine during the combustion reaction. The
powder synthesized initially was found to be amorphous based on XRD analysis. To
convert the powder into a crystalline pyrochlore structure, the powder underwent
post-calcination at various temperatures ranging from 600–1500 °C. It was
discovered that the desired monophase pyrochlore structure (A2B2O7) was obtained
after calcination at 900 °C. To create a high-density ceramic pellet, the powder
calcined at 900 °C was subjected to pressureless sintering at 1650 °C for four hours
in the presence of air. The resulting pellet had a density of 97% of the theoretical
density and was free from any additives. This process likely caused the powder
particles to fuse together, creating a solid, dense pellet.

AB  - The quest for sustainable biomaterials with excellent biocompatibility and tailorableproperties has put polyhydroxyalkanoates (PHAs) into the research spotlight. However, high productioncosts and the lack of bioactivity limit their market penetration. To address this, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was combined with a bacterial pigment with stronganticancer activity, prodigiosin (PG), to obtain functionally enhanced PHBV-based biomaterials. Thesamples were produced in the form of films 115.6–118.8  m in thickness using the solvent castingmethod. The effects of PG incorporation on the physical properties (morphology, biopolymer crystallinityand thermal stability) and functionality of the obtained biomaterials were investigated. PGhas acted as a nucleating agent, in turn affecting the degree of crystallinity, thermal stability andmorphology of the films. All samples with PG had a more organized internal structure and highermelting and degradation temperatures. The calculated degree of crystallinity of the PHBV copolymerwas 53%, while the PG1, PG3 and PG3 films had values of 64.0%, 63.9% and 69.2%, respectively.Cytotoxicity studies have shown the excellent anticancer activity of films against HCT116 (coloncancer) cells, thus advancing PHBV biomedical application potential.

AB  - The paper describes the surfacing technology for coating of high-alloyed austenitic stainless steel 316L on the steel S235JR base material. Coatings were applied by plasma transferred arc welding process. The 5 samples were made using different welding currents while other welding param-eters were constant. Metallographic analysis of the obtained samples is used to establish a correlation between the micro-structural constituents and the applied welding current in the surfacing process. According to this it was possible to determine the optimal parameters of coating surfacing. The filler material was in the form of powder, while its charac-terization was performed by scanning electron microscopy, and the characterization of the obtained coatings by optical microscopy. © 2023 Society for Structural Integrity and Life (DIVK).

AB  - In this work, the basalt deposits site from southern Serbia was used as a matrix for the composite materials. The corrosion behavior of basalt matrix composites with various ratios of commercial stainless steel 316L (5, 10, 15, and 20 wt.%) and bulk basalt produced by sintering in the air (t=1060ºC and τ=60 min) were studied by immersion corrosion technique. The samples were immersed in a solution of artificial acid rain H2SO4:HNO3 = 9:1 at ≈ pH 3 to measure the concentration of released metal ions using inductively coupled plasma-optical emission spectrometry (ICP-OES). The elements Fe, Cr, Mn, and Ni were monitored, while the others were below the limit of quantification. The concentrations of the metal ions in the solution were studied over 15 weeks. The ions release rate from all the sintered samples was found to follow the Weibull cumulative distribution function (CDF). This means that the release rate changes over time and allows us to calculate the characteristic times of ion release. The changes in the samples were monitored by light microscopy (LM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and weight loss. Sintered basalt shows high resistance to corrosion with a characteristic time of about 18 years for Fe and more than 25 years for Cr and Mn. The weight difference between the initial and after 15 weeks of exposure to the solution (sintered basalt) was not observed. On the other hand, the presence of 5 wt.% steel powder in the sintered basalt accelerates the release of metal ions by about six times. When the steel powder content in the composite materials increases, the metal release rate does not change further, but a weight loss is observed. The characteristic times for Fe, Cr, Ni, and Mn in composite materials are about 5 years. These composite materials can be investigated as materials for using in an acid environment.

AB  - Ceramic materials are often used in very aggressive and corrosive environments due to their high chemical inertness and corrosion resistance. However, even if corrosion progresses slowly, it still occurs. Corrosion usually depends on the structural properties of the materials. For example, more compact or tightly bonded materials corrode less, whether glass or crystalline materials. With the dramatic increase in nitrogen and sulphide oxide emissions, acid rain pollution has become one of the world's biggest environmental problems. One of the methods used to measure the corrosion resistance of ceramic materials and ceramic matrix composites (CMCs) is the immersion method, which studies their behaviour by immersing them in corrosive media and measuring the concentration of ions released. Adding different particles to basalt before sintering to obtain CMCs can increase fracture toughness. The aim of this work was to investigate the effects of the content of 316L stainless steel powder in sintered basalt on its structural properties and resistance to the release of metal ions in acidic environments. The andesite-basalt-based samples were prepared by adding 5, 10, 15, and 20 wt.% of steel powder, respectively, before sintering. The basalt aggregate and the pure sintered basalt served as reference materials. The metal concentrations in the solution were studied for 15 weeks at room temperature and a pH of 3.13±0.01. The major elements Fe, Cr, Mn, and Ni were monitored, while the others were below the limit of quantification. We found that the concentration of metal ions released from the basalt aggregate increases exponentially, implying that the release rate is constant over time. However, the concentration of metal ions released from the sintered samples follows the Weibull cumulative distribution function (CDF), which means that the release rate changes over time and allows us to calculate the characteristic times of ion release. The presence of 5 wt.% steel powder in the sintered basalt accelerates the release of metal ions by about six times. If the steel powder content increases, the metal release rate does not change further. These findings are positive since the highest toughness of sintered basalt is expressed at 20 wt.% of steel powder. The corrosion stability of glass-ceramic-metal-based composites was found to be satisfactory compared to natural andesite-basalt aggregate. These composites can be used in conditions of acid rain exposure where higher fracture toughness is required.

AB  - This paper presents the technological process for obtaining basalt-stainless steel composite materials and testing their physical and mechanical properties. The phases of the technological process consist of: milling, homogenization, pressing, and sintering to obtain composite materials with improved fracture toughness. Andesite basalt from the deposit site "Donje Jarinje", Serbia, was used as a matrix in the composites, while commercial austenitic stainless steel 316L in the amount of 0-30 wt.% was used as a reinforcement. Although the increase of 316L amount caused a continuous decrease in the relative density of sintered samples, the relative density of sample containing 30 wt.% of 316L was above 94%. The 316L grains, which possess a larger coefficient of thermal expansion than the basalt matrix, shrinking faster during cooling from sintering temperature resulting in the formation of compressive residual stress in the basalt matrix surrounding the spherical steel grains. The presence of this stress activated toughening mechanisms such as crack deflection and toughening due to compressive residual stress. The addition of 20 wt.% of reinforcing 316L particles increased the fracture toughness of basalt by more than 30%. The relative density of these samples was measured to be 97%, whereas macrohardness was found to be 6.2 GPa.

AB  - In modern industry, there is an increasing demand for environmentally friendly and light structural materials with good physical and mechanical properties, produced from cheap natural raw materials available in large quantities. One of the materials that meet the mentioned criteria is basalt. Basalt is a natural igneous rock of volcanic origin, created by the pouring of magma on the Earth's surface, the amount of which is significant in the territory of Serbia. Since basalt does not exhibit toxic, carcinogenic, or mutagenic effects, it is in the true sense a non-hazardous material and belongs to the group of eco-friendly materials. In this research, andesite basalt aggregate from the "Donje Jarinje" site, in Serbia, was used to obtain high-density glass-ceramic materials. High-density glass-ceramic materials were obtained by powder metallurgy process, which consisted of the following methods: dry grinding, homogenization, cold uniaxial and isostatic powder pressing and sintering in the air. In order to achieve a high-density of the materials, the green compacts were sintered in the temperature range from 1040 to 1080 °C. After confirming that the highest density materials were achieved at the sintering temperature of 1060 °C, the sintering time was optimized in the time interval from 30 to 240 min. After the experimental test, the optimal sintering parameters for obtaining high-density glass-ceramic material at the temperature of 1060 °C for 60 min were achieved, whose relative density is 99.50%, and hardness is 6.70 GPa. The characterization of andesite basalt powder was performed using the laser light diffraction method, scanning electron microscopy and X-ray diffraction method, while the characterization of sintered glass-ceramic materials was performed using the Archimedes method, X-ray diffraction method, optical light microscopy and Vickers hardness test. The results of this research confirmed that by applying powder metallurgy and sintering in the air, high-density glass-ceramic materials could be obtained for various industrial applications in the civil engineering, chemical and food industries, as well as for the making of containers for the storage of nuclear waste. Also, high-density glass-ceramic materials would be suitable for making a matrix in modern composite materials.

AB  - The industrial requirements in the 21st century are environmentally friendly and light construction materials with good physical-mechanical properties manufactured from cheap natural raw materials available in large quantities. One of these materials is basalt. Basalt is a natural igneous rock of volcanic origin, with a significant amount in Serbia. Basalt belongs to the group of non-hazardous and eco-friendly materials. Andesite basalt aggregate from the "Donje Jarinje" site, Serbia, was used as the starting natural raw material for obtaining the glass-ceramic material. The aggregate is from 2 to 5 mm in size. The aggregate was milled in the tungsten-carbide vibrating cup mill for 30 min to obtain a fine powder for synthesis. The homogenization of andesite basalt powder and binder was carried out in the mortar and pestle for 10 min. The paraplast was used as a binder with a content of 0.6 wt.%. After that, uniaxial pressing of the powder at a pressure of 50 MPa was performed. A forming green compact, cold isostatic pressing was performed with a pressure of 230 MPa to increase its density. The sintering was carried out at the temperature of 1060 °C for 60 min in the air. The sintered glass-ceramic sample was a relative density of 99.5%, a macrohardness of 6.7 GPa and a fracture toughness of 2.2 MPa·m1/2 [1]. The andesite basalt powder was characterized using the laser light diffraction method, X-ray diffraction method and scanning electron microscopy. Sintered glassceramic material was characterized using the X-ray diffraction method, Archimedes principle, scanning electron and optical light microscopy and the Vickers hardness test. The glass-ceramic material obtained by sintering andesite basalt powder could be used for various industrial applications in the civil engineering, mechanical, chemical, and petrochemical industries, as well as for the making of containers to store nuclear waste.

AB  - The modern transportation industry is in high demand for lightweight structural components with exceptional mechanical properties that can be obtained by a costeffective production process. These specific industrial requirements can be achieved through the attainment of innovative aluminum matrix composites (AMCs) with improved characteristics in accordance with the circular economy. Solid-state recycling is considered a good solution to attain the above-mentioned industrialdemands since it enables the obtainment of usable and inexpensive raw materials with known chemical composition from industrial waste and therefore supports the cost-effective production of structural components. The present research was, therefore, directed toward the repurposing of waste materials derived from the metal industry and the civil engineering sector through a simple and economical solid-state recycling procedure to obtain raw materials for the production of innovative AMCs with required characteristics. The aluminum 2xxx series alloy, i.e. 2024 alloy, in the form of metallic chips generated during the industrial machining was selected for the obtainment of composite base, while basalt fibers derived from stone mineral wool, as waste material in civil engineering, were used to produce the composite reinforcing phase. Basalt, characterized by high strength and low density, provides improved resistance to chemical and mechanical damage, while the 2024 alloy contributes to good fatigue properties of the final fiber-reinforced AMCs. To obtain usable raw materials for the AMCs preparation from the solid industrial waste the basalt fibers were thermally treated, while aluminum-based metallic chips were ballmilled. Treated aluminum alloy powder and basalt fibers were mixed in a 3D tumbler mixer in a 9:1 ratio, isostatically pressed, and sintered in a protective argon atmosphere at 550 °C. Isostatic pressure and sintering duration were varied during the AMCs preparation to determine the optimal processing parameters for the obtainment of AMCs with the required characteristics for a predetermined purpose. The scanning electron microscopic (SEM), energy dispersive spectroscopic (EDS), and X-ray diffraction (XRD) analyses complemented with hardness and density measurements were conducted to characterize starting and final materials. Obtained composites showed improved mechanical properties compared to the starting aluminum alloy, regardless of the processing conditions. The AMCs processed at a higher pressure and for longer sintering times showed higher density and hardness. The results of the presented research undoubtedly indicated that solid-state recycling, as a simple, energy- and cost-efficient process, can be successfully used for the attainment of innovative composites for lightweight structural components in the transportation industry.

AB  - Tin dendrites found wide application in various industries.1 They can be obtained by both non-electrochemical and electrochemical methods of synthesis. In this study, they were produced by a galvanostatic regime of electrolysis from alkaline hydroxide solution at a current density of –3 mA cm–2 , 1.5 times larger than the limiting diffusion current density, with an amount of the electricity of 200 and 400 mC. In the dependence of an amount of the passed electricity, Sn dendrites of various morphology and crystal orientation were obtained: the fern-like dendrites predominantly oriented in (220), (440) crystal planes are obtained with 200 mC and the spear-like and the dendrites with prismatic branches showing the strong (200),(400) preferred orientationwere obtained with 400 mC. The strong correlation between morphology and structure of Sn dendrites is established and it can be explained by analysis of chronopotentiometry response obtained at the given current density and by morphological and structural analyses of Sn dendrites obtained by a potentiostatic regime at cathodic potentials corresponding to values attained after the passed amount of the electricity of 200 and 400 mC. The chronopotentiometry response after spent 200 mC was dominantly in the (–1600 – 1740) mV vs. Ag/AgCl range, and the fern-like dendrites with the strong (220), (440) preferred orientation were obtained in this potential range. After spent 400 mC, the chronopotentiometry response was about –1200 mV vs. Ag/AgCl, and the spear-like and the dendrites with prismatic branches with the strong (200),(400) preferred orientationwere obtained at this cathodic potential.

AB  - In order to achieve widespread application of fuel cell technology, the development of an efficient and economical catalyst is a crucial step. Reducing the diameter of catalyst particles, producing particles with a specific orientation surface, and alloying noble metals with less expensive metals are possible approaches to improve catalyst performance. This study will be focused on novel ways for creating PtSnZn catalysts that are more effective for the anodic reactions in fuel cell such are methanol, ethanol and formic acid oxidation reactions. PtZn and PtSnZn nanoparticles were produced using the microwave assisted polyol method and were supported on high surface area carbon Vulcan XC-72R material. The electrochemical behavior of synthesized catalysts was investigated utilizing the cyclic voltammetry, chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission electron microscopy analysis (TEM), and thermogravimetric analysis (TGA) were used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the benefits of microwave synthesis and carefully adjusted metal alloying.

AB  - The influence of chronopotentiometry response on the morphology and structure of galvanostatically synthesized tin dendriticparticles has been investigated. Sn dendrites were electrodeposited at the current density 1.5 times larger than the limiting diffusioncurrent density (− 3 mA cm−2) with various amounts of the electricity (200 and 400 mC), and the obtained morphologyand structure of the particles were characterized by SEM and XRD techniques, respectively. The strong effect of the amountof spent electricity on the morphology and structure of the particles was observed, and it is explained by morphological andstructural analysis of Sn particles produced potentiostatically at various cathodic potentials selected to be in line with therecorded chronopotentiometry response. The strong correlation among chronopotentiometry response, morphology, andstructure of the Sn dendrites was established. The spear-like and the dendrites with prismatic branches possessed the strong(200),(400) preferred orientation, and they were obtained with a chronopotentiometry response of about − 1200 mV vs. Ag/AgCl. The chronopotentiometry responses in the − 1210 ÷ − 1740 mV vs. Ag/AgCl range caused a formation of the fern-likedendrites with the strong (220),(440) preferred orientation. Based on the obtained results, it follows that the chronopotentiometryanalysis represents good diagnostic criteria for obtaining Sn powder particles of desired morphology and structure.

AB  - In this study, two high chromium cast irons (HCCI) with different chromium content (15%Cr and 25%Cr), in as-cast and annealed conditions (heat-treated, HT), were tested to determine the erosion wear behavior of these alloys. Erosion tests were done using a gas blast sand facility with high erodent particle velocity (90 m/s) and high erodent feed rate, at an impact angle of 45°, which represents conditions similar to service conditions of some components of thermal power plants using pulverized high mineral content coals. To identify erosion mechanisms, microstructural characterization was done by a scanning electron microscope on samples before and after erosion tests. Identification of microstructural phases was done by X-ray diffraction analysis. The main results of the tests shown in this paper indicate that matrix plastic deformation and distribution of carbide phase have a significant contribution to erosion resistance of HCCI alloys in severe erosion service conditions.

AB  - This work highlights the potential for the synthesis of new PtSnZn catalysts with enhanced efficiency and durability for methanol oxidation reaction (MOR) in low-temperature fuel cells. In this research, PtZn and PtSnZn nanoparticles deposited on high surface area Vulcan XC-72R Carbon support were created by a microwave-assisted polyol method. The electrochemical performances of synthesized catalysts were analyzed by cyclic voltammetry and by the electrooxidation of adsorbed CO and the chronoamperometric method. The physicochemical properties of obtained catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TGA) analysis, energy dispersive spectroscopy (EDS) and by X-ray diffraction (XRD). The obtained findings showed the successful synthesis of platinum-based catalysts. It was established that PtSnZn/C and PtZn/C catalysts have high electrocatalytic performance in methanol oxidation reactions. Catalysts stability tests were obtained by chronoamperometry. Stability tests also confirmed decreased poisoning and indicated improved stability and better tolerance to CO-like intermediate species. According to activity and stability measurements, the PtSnZn/C catalyst possesses the best electrochemical properties for the methanol oxidation reaction. The observed great electrocatalytic activity in the methanol oxidation reaction of synthesized catalysts can be attributed to the beneficial effects of microwave synthesis and the well-balanced addition of alloying metals in PtSnZn/C catalysts.

AB  - One of the most responsible elements of modern steam boilers are steam superheaters and reheaters.
These heating surfaces are inside the boiler chamber and consist of tubes connected to the inlet and
outlet header. Due to the complexity of service conditions, boiler tubes are exposed to processes of
gradual degradation, and consequently a decrease in operating performance and reliability.
In the operation of thermal power plants, irreversible metal losses resulting from corrosion can
cause tube failure and plant outage. Considering the loss of materials, gas corrosion in the dry gas
atmosphere due to the high temperature is of great importance. Gas corrosion can be expressed in
the boiler tubing system due to the presence of sulfur compounds in the flue gases. For this reason,
it must be borne in mind that the outer surface of a tube of final reheater has different damage
mechanisms during operation, and one of them is gas corrosion. Gas corrosion causes material loss
and provides a site for crack initiation and propagation, which can compromise the integrity of the
pressure vessel.
In this paper, a tube of a final reheater from a 210 MW power plant was tested. The tube was in
service 200,000 h at a working temperature of 540 °C and a maximum working pressure of 4.6
MPa. The tube is made of low alloy Cr-Mo-V steel, class 12H1MF (GOST). After long-term
service, a rough surface and loss of the material in the form of a crater were observed on the outer
surface of the tube as a result of the effect of gas corrosion, together with the change of
microstructure due to elevated service temperature. The measured depth of damage to the tube is
120 m. The presence of gas corrosion on the tube was confirmed and measured by an optical
microscope, Figure 1.

AB  - In the present study, andesite basalt originated from the deposit site “Donje Jarinje”, Serbia, was examined as a potential raw material for high-density ceramics production. The production of high-density ceramics included dry milling, homogenization, cold isostatic pressing and sintering in the air. To determine the optimal processing parameters the sintering was conducted at 1040, 1050, 1060, 1070 and 1080°C, and afterwards the sintering duration was varied from 30 to 240min at the optimal sintering temperature of 1060°C. Characterization of the starting and sintered materials included the estimation of particle size distribution, density, hardness and fracture toughness complemented with X-ray diffraction, optical light microscopy, scanning electron microscopy and energy dispersive spectroscopy analysis. Phase transformations did not occur during processing in the investigated temperature range from 1040 to 1080°C. The obtained research results showed that 99.5% of relative density and the highest hardness and fracture toughness values of 6.7GPa and 2.2MPa•m1/2, respectively, were achieved for the andesite basalt sintered at 1060°C for 60min in the air. The results of the present study confirmed that the sintered andesite basalt can be used as a high-density ceramic material for various industrial applications.

AB  - The Ni-Cr dental alloys are among the oldest restorative materials used in dentistry. Reuse of previously melted and cast dental alloys is a routine procedure used in dental laboratories to reduce the cost of dental restorations. Continuous reuse of the commercial Ni-Cr dental alloys, such as Wirron 99, can change numerous properties of these materials, and therefore the present study was aimed to establish the outcome of several recasting cycles on the Wirron 99 alloy properties. Obtained results reveal that alloy recasting resulted in the appearance of typical dendritic microstructures where the chemical composition of dendritic and interdendritic regions differs. Moreover, the results of the present study showed that the number of recasting cycles has a significant effect on the alloy microstructure, structure, electrical conductivity, and hardness

Moreover, the results of the present study showed that the number of recasting cycles has a significant effect on the alloy microstructure, structure, electrical conductivity, and hardness",

AB  - The aim of this paper is to examine the physical and mechanical properties of glass-ceramic-metal composite materials obtained by sintering. Andesite basalt rock from Serbia was used as the starting material for obtaining the glass-ceramic matrix. Commercial powder of austenitic stainless steel 316L in the content of 10, 20, and 30 wt. % was used as the reinforcement. The technological process for obtaining glass-ceramic-metal composite materials consists of the following phases: crushing of andesite basalt rock to obtain the fine powder, homogenization of andesite basalt powder and 316L stainless steel powder with a binder, uniaxial pressing of powders with the pressure of 50 MPa, cold isostatic pressing green compacts with the pressure of 230 MPa, and sintering at 1060 °C/1h in the air. Based on the obtained experimental results, it could be concluded that the relative density of the sintered composite materials decreases with the increasing content of 316L steel in the glass-ceramic matrix. Also, there is a hardness decrease of the composite materials with increased content of 316L steel, which is expected due to the reduction in the relative density. However, the fracture toughness increases with increasing 316L steel content in the composite materials. The presence of a metal reinforcer in the glass-ceramic matrix contributed to the increase of fracture toughness of composite materials and thus the prevention of the catastrophic fracture common in glass-ceramic
AB  - Cilj ovog rada je ispitivanje fizičko-mehaničkih svojstava kompozitnih materijala staklo-keramikametal dobijenih sinterovanjem. Kao polazni materijal za dobijanje staklo-keramičke matrice korišćena je andezit bazaltna stena iz Srbije, dok je kao ojačivač korišćen prah komercijalnog austenitnog nerđajućeg čelika 316L sadržaja 10, 20 i 30 tež. %. Tehnološki proces dobijanja kompozitnih materijala staklo-keramika-metal sastoji se iz sledećih faza: drobljenja andezit bazaltne stene u cilju dobijanja finog praha, homogenizacije andezit bazaltnog praha i praha nerđajućeg čelika 316L sa vezivom, jednoosnog presovanja pritiskom od 50 MPa, hladnog izostatičkog presovanja pritiskom od 230 MPa i sinterovanja na 1060 °C/1h u vazduhu. Na osnovu dobijenih eksperimentalnih rezultata može se zaključiti da se relativna gustina sinterovanih kompozitnih materijala smanjuje sa povećanjem sadržaja čelika 316L u staklo-keramičkoj matrici. Takođe, dolazi do smanjenja tvrdoće kompozitnih materijala sa povećanjem sadržaja čelika 316L u kompozitu, zbog smanjenja relativne gustine. Sa povećanjem sadržaja čelika 316L u kompozitnom materijalu žilavost loma se povećava. Prisustvo metalnog ojačivača u staklo-keramičkoj matrici doprinelo je povećanju žilavosti loma kompozitnih materijala i prevenciji loma koji je uobičajen u staklo-keramici.
