Abstract
The effect of oxygen content on the mechanical and thermal properties of Zr57Nb5Al10Cu15.4Ni12.6 bulk metallic glass was measured. Oxygen was systematically added to a master alloy through the addition of ZrO2. Compression, Vickers hardness and bending, differential scanning calorimetry (DSC) and X-ray measurements were performed. Material with no additional oxygen demonstrated the ability to deform through multiple shear band formation, while that with higher oxygen content retained up to 90% of its compressive strength but lost virtually all ductility. The loss of ductility is attributed to the formation of Zr2Cu- and Zr2Ni-type intermetallic oxide particles.
