Abstract The compositional dependence of the yield strength σy has been studied for a series of polycrystalline ( AuNiPdPt ) 1 − x Cu x alloys by means of compression tests. σy is found to decrease linearly with increasing Cu concentration. This behaviour is in contradiction to the generalised theory for solid solution strengthening in concentrated solid solutions provided by Varvenne et al. [1]. A breakdown of the scaling behaviour is found as σy should be non-linear and slightly increasing when modifying the composition from AuNiPdPt to AuCuNiPdPt.

(AuNiPdPt)1−xCu 高熵合金中 Varvenne 结垢的分解

摘要 已经通过压缩试验研究了一系列多晶 (AuNiPdPt) 1 - x Cu x 合金的屈服强度 σy 的成分依赖性。发现σy 随Cu 浓度的增加而线性降低。这种行为与 Varvenne 等人提供的浓缩固溶体中固溶强化的广义理论相矛盾。[1]。当将成分从 AuNiPdPt 修改为 AuCuNiPdPt 时，发现缩放行为的崩溃是因为 σy 应该是非线性的并且略有增加。
