Investigations of compressive strength on Cu-Hf-Al bulk metallic glasses: Compositional dependence of malleability and Weibull statistics

► We investigated the malleability of the Cu91-xHfxAl9 (39≤x<46) series BMGs. ► As Hf content increases, the series BMGs show higher compressive malleability. ► Shear stress mainly controls the compressive deformation behaviors for these BMGs. ► The malleability has no directly correlation with Poisson's ratio and GFA.
