Oxidation features of plastic deformed Zr-based bulk metallic glass

► In this work, we investigate the effect of plastic deformation on the oxidation morphology of Zr47.9Ti0.3Ni3.1Cu39.3Al9.4 bulk metallic glass at elevated temperatures. ► In situ formed and pre-existed shear bands are found to be more susceptible to oxidation than the matrix. ► Crystallization improves the oxidation resistance significantlly.
