摘要：
We study the influence of electron concentration, lattice distortion, and phase ratio on the hardness, elasticity modulus, and normalized hardness of high-entropy two-phase alloys. It is shown that the fractions of phases depend on the concentrations of electrons. A sharp increase in the FCC phase is observed for electronic concentrations higher than 8 el/at. For high-entropy two-phase alloys, we establish a linear dependence of the normalized hardness on the dimensional mismatch. The values of normalized hardness increase from 0.025 to 0.043 as the level of distortion increases from 2.3 to 4.3%.
