摘要: Using ab initio alloy theory, we investigate the equilibrium bulk properties and elastic mechanics of single bcc solid-solution AlxHf1−xNbTaTiZr (x = 0–0.7, 1.0) high entropy alloys. Ab predicted volume is consistent with available experiment. We make a detailed investigation alloying effect Al Hf on volume, constants polycrystalline moduli. Results imply that partial replacement increases stability phase decreases ductility HEAs. The inner Al0.4Hf0.6NbTaTiZr by calculations ideal tensile strength.
