AB  - Copper-zirconium alloys with high conductivity were produced using powder metallurgy. Two-steps manufacturing process, containing mechanical alloying followed by hot pressing, was applied in achieving improved mechanical and physical properties of Cu-Zr alloy. In this paper, the influence of boron on Cu-Zr alloys properties was studied on Cu-1Zr (wt.%) and Cu-1.1Zr-0.3B (wt.%) systems. Scanning electron microscopy, laser nanoparticle sizer, computed tomography and X-ray diffraction were employed for observation of changes in the microstructure during production steps. More specifically – variations in size of the Cu particles, powder mixtures’ structural parameters, and development of CuZr phase in binary alloy, CuZr phase and ZrB2 particles in ternary alloy were observed. It was shown that presence of boron increases dislocation density in ternary alloy over the mechanical alloying time compared to binary alloy. The results presented in this study show higher hardening effect in Cu-Zr-B alloy compared to Cu-Zr alloy, resulting in stable hardness values during thermomechanical treatment. Further, it can be seen that finely dispersed reinforcing ZrB2 particles in copper matrix does not have significant influence on its conductivity. Moreover, both systems Cu-Zr and Cu-Zr-B exhibit better electrical conductivity after thermomechanical treatment as a result of zirconium reduction in solid solution due to its precipitation.

AB  - Copper-zirconium alloys with the minor addition of boron were manufactured using powder metallurgy, combining mechanical alloying, hot pressing, and sintering. The influence of boron on the mechanical properties of the Cu-Zr alloys was studied on Cu-1Zr (wt.%) and Cu-1.1Zr-0.3B (wt.%) systems. Scanning electron microscopy (SEM), laser nanoparticle sizer, computed tomography, and X-ray diffraction were employed for the observation of morphological and structural changes in the copper microstructure during manufacturing, as well as the development of CuZr phase and ZrB2 particles. Based on SEM and X-ray diffraction analysis, it can be seen that finely dispersed reinforcing ZrB2 particles in copper matrix occur only after the hot pressing process, and not during mechanical alloying. Mechanical properties of the copper-zirconium alloys were investigated using nanoindentation and microhardness tests. It was shown that the presence of a small boron amount, less than 3 wt.%, increases dislocation density in Cu-Zr-B powder mixture with increasing the duration of mechanical alloying. Moreover, analysis of the obtained results reviled that the addition of boron induces a higher hardening effect in Cu-Zr-B alloy compared to CuZr alloy, which results in more stable hardness values during thermomechanical treatment.

AB  - In this study, the Cu-Zr-B ternary system was investigated as it has proven to be a promising composite material used in various industries, including aerospace, automotive, electronics, nuclear and tooling, among others. Owing to its versatility and a combination of desirable properties such as high strength and hardness, corrosion and wear resistance, and thermal stability, making it suitable for a wide range of applications. The effects of mechanical alloying (MA) parameters on the Cu-Zr-B properties, including ball-to-powder ratio, rotation speed, milling time, and milling atmosphere, were examined using the X-ray analysis, scanning electron microscopy, stereological analysis, and the Williamson-Hall analysis. Different mills, namely Atritor Mill and Turbula Shaker, were used in order to determine the effect that the type of mill has on the final structural parameters of the Cu-Zr-B. All results are given after 20 hours of mechanical alloying of the composite material. The rotation speed was around 300 rpm for both devices, and the ball-to-powder ratio was 10:1 for all the cases. It was shown that the ball size also plays a significant role in the final microstructural and morphological properties of the MA powders of the Cu-Zr-B. A comprehensive analysis showed that the powders produced in the Atritor mill (Powder 1, with a uniform ball size), as well as the powders produced in the Turbula where there was a range of different ball sizes used (Powder 2), showed lower values of dislocation density and crystalline size values compared to the powders produced in the Turbula with a uniform ball size (Powder 3). It is important to state that, with time, due to the plastic deformation mechanisms present, crystallite size decreases in all cases, with the lowest value again being powder 3.

AB  - Copper matrix composites exhibit excellent mechanical and thermal properties. The composite consists of copper (Cu), zirconium (Zr), and boron (B) and is produced using the powder metallurgy technique. The high-energy ball milling was applied for mechanical alloying of the Cu-Zr-B powder mixture to achieve the desired ratio for obtaining a copper matrix reinforced with ZrB2 ceramic particles. The milling times of 10 and 40 hours for two different ball-to-powder ratios are investigated for a powder mixture with a composition of Cu-2.71Zr-2.27B (wt.%). XRD and SEM analyses were employed to determine structural and morphological changes in the mechanically alloyed powder mixture. Investigation of the morphological parameters shows that with prolonged milling, the shape of mixed particles becomes more uniform, while their structural parameters have been drastically changed. It is determined that during high-energy ball milling of the Cu-2.71Zr-2.27B (wt.%), the size of the copper powder decreases as the mechanical alloying increases for both ball-powder ratios. Dislocation densities reach their maximum value at around 30 hours of mechanical alloying for both ball-powder ratios, with dislocation density being higher for the 1:15 ratio, after which they decrease owing to the recrystallization of the copper matrix. XRD analysis shows no presence of ZrB2 reinforcement particles or oxides during milling.

AB  - In powder form, copper (Cu) is the most used element in alloys and composites thanks to its affordability, availability, and capacity to easily improve its properties by adding just a few other elements [1]. It is then of no surprise that Cu composite materials find their application in various industries such as medical devices, aerospace, defense, automotive parts and electronics [2]. In this instance, a hybrid ternary Cu-2wt%Zr0.6wt%B composite was designed. Mechanical alloying (MA) was used to produce adequate powders for further composite manufacturing. The MA process was conducted in two different devices, Atritor Mill and Turbula Shaker Mixer, to determine the effect that the mixing type has on the final material. The milling parameters were set as (i.) duration for 10 h, 20 h, 30 h, and 40 h, (ii.) ball-to-powder ratio was 10:1, (iii.) inert atmosphere - argon. Electron microscopy and X-ray diffraction were used to investigate the microstructural and morphological properties of the Cu-Zr-B MA powder. Obtained results indicate that MA powders produced in Atritor show lower values of structural parameters (crystallite size, lattice parameter and lattice strain) compared to one in Turbula up to 30 h of milling. It should be noted that values of structural parameters after 40 h of milling in Turbula are lower compared to those in Atritor due to the recrystallization of Cu particles. Based on XRD results, the dislocation densities (ρ) were calculated and exhibited that MA powders milled in Atritor possess lower ρ values compared to MA powders milled in Turbula, except ρ of MA powders after 40 h. Higher values of observed structural parameters of MA powders revealed that during milling in Turbula, powders have been exposed to stronger forces in ball-powder-ball and ballpowder-wall collisions.

The MA process was conducted in two different devices, Atritor Mill and Turbula Shaker Mixer, to determine the effect that the mixing type has on the final material. The milling parameters were set as (i.) duration for 10 h, 20 h, 30 h, and 40 h, (ii.) ball-to-powder ratio was 10:1, (iii.) inert atmosphere - argon. Electron microscopy and X-ray diffraction were used to investigate the microstructural and morphological properties of the Cu-Zr-B MA powder. Obtained results indicate that MA powders produced in Atritor show lower values of structural parameters (crystallite size, lattice parameter and lattice strain) compared to one in Turbula up to 30 h of milling. It should be noted that values of structural parameters after 40 h of milling in Turbula are lower compared to those in Atritor due to the recrystallization of Cu particles. Based on XRD results, the dislocation densities (ρ) were calculated and exhibited that MA powders milled in Atritor possess lower ρ values compared to MA powders milled in Turbula, except ρ of MA powders after 40 h. Higher values of observed structural parameters of MA powders revealed that during milling in Turbula, powders have been exposed to stronger forces in ball-powder-ball and ballpowder-wall collisions.",

AB  - Ternary Cu-2.71Zr-2.27B (wt.%) alloys were fabricated using powder metallurgy, i.e., mechanical alloying followed by cold pressing and sintering. Influence of the mechanical alloying parameters on microstructural and morphological changes of Cu-Zr-B powder mixture was investigated using scanning electron microscopy and X-ray diffraction. Stereological analysis was employed to determine changes in size and shape of copper particles during 40 hours of mechanical alloying. It was shown that with an increase in mechanical alloying time, the size of copper powder decreases. Williamson-Hall analysis was used to calculate crystallite sizes (D, nm), lattice parameter (nm), lattice strain (ε, %), and dislocation density (ρ, m-2). It was shown that with increasing mechanical allo ying time, lattice parameter as well as lattice strain both increases. Particles undergo high forces through ball-particle-ball and wall-particle-ball collisions during mechanical alloying. These collisions induce accumulation of dislocations in copper matrix and a decreasing in its crystallite size due to dominant plastic deformation mechanisms. Dislocation densities reach its maximum value at around 30 hours of mechanical alloying, after which they decrease owing to the recrystallization of copper matrix.

AB  - Metal matrix composites (MMCs) belong to a group of modern materials owing to their excellent technological, mechanical, and physical properties such as excellent wear and corrosion resistance, high electrical and thermal conductivity, improved strength and hardness. Final properties of MMCs are affected equally by all steps of its manufacturing process. It is shown that by using adequate process parameters to obtain starting materials (reaching the specific size, shape, and reactivity) the control of volume fraction and distribution of reinforcements within the matrix can be achieved. For this purpose, mechanical alloying has been appointed as a good approach. MMCs can be produced using powder metallurgy, ingot metallurgy, and additive manufacturing techniques. Combining high-energy ball milling with these techniques enables the design of an innovative processing route for MMCs manufacturing. Mechanochemical process (achieved using high-energy ball milling) was employed in three manufacturing procedures: hot pressing, compocasting, and laser melting/sintering for obtaining of the suitable powder. These production routes for MMCs manufacturing were the subject of this work. The aim of MMCs design is to establish an optimal combination of production techniques merged into the cost-effective fabrication route for obtaining MMCs with required properties.

AB  - Copper-based alloys and composites, owing to their convenient properties, are being considered essential materials in various industries. Since copper possesses an ability to develop high corrosion resistance, putting it in the domain of a desirable material in the manufacturing of valves, pipes, and also systems that carry industrial gases and aqueous fluids. Its usage is also invaluable for cables and electrical wires. This review paper describes diversity in copper alloy processing techniques (powder and ingot metallurgy) which are alongside the phase transformation kinetics interpreted and explained in detail. Furthermore, the focus is put on the copper alloys, as well as the kinetics present in these systems, with the application being highlighted. Correlation between physical properties and phase transformation kinetics in copper alloys is made. It is shown that if certain alloying elements are to be added, different properties could be improved. The effect of phase precipitation on phase transformation kinetics of copper alloys is shown by studying the Cu–15Ni–8Sn alloy.

AB  - High-temperature materials are used in a wide range of industries and applications such as gas turbine engines for aircrafts, power and nuclear power plants, different types of furnaces, including blast furnaces, some fuel cells, industrial gas turbines, different types of reactors, engines, electronic and lighting devices, and many others. Demands for high-temperature materials are becoming more and more challenging every year. To perform efficiently, effectively and at the same time to be economically viable, the materials used at high temperatures must have certain characteristics that are particularly expected for applying under such extreme conditions, for example, the strength and thermal resistance. In the present review, some important requirements that should be satisfied by high temperature materials will be discussed. Furthermore, the focus is put on refractory concretes, ceramics, intermetallic alloys, and composites as four different categories of these materials, which are also considered in respect to possibilities to overcome some of the current challenges.
