Microstructure and Mechanical Behavior of CrFeNi2V0.5Wx (x = 0, 0.25) High-Entropy Alloys

CrFeNi2V0.5Wx (x = 0, 0.25) alloys based on these parameters of mixing enthalpy (ΔHmix), mixing entropy (ΔSmix), atomic radius difference (δ), valance electron concentration, and electronegativity difference(Δχ) were designed and prepared. The microstructure and room-temperature mechanical behavior of both alloys were investigated. Compressive test results showed that the CrFeNi2V0.5W0.25 alloy had higher yield strength than that of the W-free...
