Kurzbeschreibung (Abstract)
The compositional dependence of the yield strength σ_y has been studied for a series of polycrystalline (AuNiPdPt)_1-xCu_x alloys by means of compression tests. σ_y 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 σ_y should be non-linear and slightly increasing when modifying the composition from AuNiPdPt to AuCuNiPdPt.
