High-entropy alloys (HEAs) prefer to form single-phase solid solutions (body-centered cubic
(BCC), face-centered cubic (FCC), or hexagonal closed-packed (HCP)) due to their high
mixing entropy. In this paper, we systematically review the mechanical behaviors and
properties (such as oxidation and corrosion) of BCC-structured HEAs. The mechanical
properties at room temperature and high temperatures of samples prepared by different
processes (including vacuum arc-melting, powder sintering and additive manufacturing) are …
