Compositions with minimal Gibbs free energy for single- and multi-phase high-entropy alloys (HEAs) containing Ni, Co, Fe, Cr, Cu, Al, Mn, Ti, Zr, V elements are developed using a developed thermodynamic approach. The phase compositions for some equiatomic HEAs are predicted and the influence of various factors on its formation are described. A correlation between theoretical and experimental data is obtained. Criteria for search of HEAs compositions favourable for formation of single-phase and multi-phase solid solutions are formulated.
Key words: thermodynamic prediction, high-entropy alloys, solid solution, intermetallic compounds.
