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.
