( KJS-15-7004) Plastic Deformation of Single Crystals of the CrMnFeCoNi High-Entropy Alloy

摘要

High entropy alloys (HEAs) are equiatomic or nearly equiatomic solid solution alloys consisting of at leastfive elements1. These alloys may exist as a stable single-phase because the contribution of configurationalentropy to the Gibbs free energy may be high enough to suppress compound formation and phase separation.HEAs are known to exhibit various interesting properties: very low diffusion coefficients2, excellenthigh-temperature strength3, and so on. Especially, the equiatomic CrMnFeCoNi HEA with the FCC structurehas been reported to exhibit excellent ductility4,5 and exceptional fracture toughness at cryogenictemperatures6.
