摘要

通过热机械加工的方法，设计了一种具有非均匀晶粒组织和纳米级析出的Al0.3CoCrNi中熵合金，旨在实现低温屈服强度和延展性的显著结合。该合金具有优异的低温屈服强度(~ 1.1 GPa)和均匀伸长率(~ 37%)。

Exceptional cryogenic strength-ductility synergy in Al0.3CoCrNi medium-entropy alloy through heterogeneous grain structure and nano-scale precipitates

We engineered an Al_0.3CoCrNi medium-entropy alloy with heterogeneous grain structure and nanoscale precipitation through thermo-mechanical processing route, with an aim to achieve a remarkable combination of cryogenic yield strength and ductility. The alloy exhibited an exceptional combination of high cryogenic yield strength of ∼1.1 GPa and high uniform elongation of ∼37%.
