| Popis: | The method for design of stabile multicomponent solid solutions with use thermodynamic, mechanical and topological parameters of the constituent elements was developed. The alloys based on W, Ta, Mo, Nb, V, Ti, Zr, Hf and Cr elements were investigated using this approach. Optimal compositions for high entropy alloys were obtained and influence of various factors on formation of stable alloys was described. It is shown that the most resistant alloys have non equiatomic element ratios. The agreement between element distributions in experimental alloys and predicted stable compositions were received for alloys of W-Ta-Mo-Nb and W-Ta-Mo-Nb-V systems. |
