Myslyvchenko O. The features of structure formation and properties of high-entropy alloys of the Cr-Al-Fe-Co-Ni-Cu-Mn-V system

Dissertation is devoted to the solution of scientific and technical problem on finding of the new multicomponent alloys, having dipped properties. The features of the structure and properties of high-entropy alloys of Cr-Al-Fe-Co-Ni-Cu-Mn-V. The effect of additional doping on their phase composition, microstructure and physical and mechanical properties. Developed six component alloy CrMnFeCoNi2Cu with high deformability. The influence of strain on alloy phase composition, texture, microstructure, physical and mechanical properties and high thermal stability shown in these figures. The conditions of formation of sigma-phase multicomponent alloys. Based on these conditions, the system of alloys containing sigma-phase studied their phase composition, microstructure, physical and mechanical properties and wear resistance. Keywords: high-entropy alloys, crystal structure, solid solution strengthening, мicrostructure, microhardness, Young's modulus, сold rolling, texture, annealing, thermal stability, wear.
