AB  - In many industrial processes that include fluid flow, cavitation erosion of different engineeringstructures (pumps, turbines, water levels, valves, etc.) during their operation is expected. Metallic,ceramic, and composite materials are usual candidates considered for application in such extremeconditions. In this study, the idea is to synthesize refractory ceramic material based on talc withthe addition of zeolite for utilization as protective coatings in cavitating conditions. Two talc-basedrefractories with zeolites from two Serbian deposits were produced. The behaviors of the samplesin simulated cavitation conditions were examined by an advanced non-destructive methodologyconsisting of monitoring mass loss and surface degradation using image analysis compiled withprincipal component analysis (PCA), interior degradation by ultrasonic measurements, and themicrostructure by a scanning electron microscope (SEM). Lower mass loss, surface degradation level,and modeled strength decrease indicated better cavitation resistance of the sample with Igros zeolite,whereby measured strength values validated the model. For the chosen critical strength, the criticalcavitation period as well as critical morphological descriptors, Area and Diameter (max and min),were determined. A Young’s elasticity modulus decrease indicated that surface damage influenceprogressed towards interior of the material. It can be concluded that the proposed methodologyapproach is efficient and reliable in predicting the materials’ service life in extreme conditions.

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  - 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.
