Toughness of Zr55Cu30Al10Ni5 bulk metallic glass for two oxygen levels

This paper demonstrates the embrittlement of a Zr-based bulk metallic glass caused by the presence of very low oxygen traces during its synthesis. Toughness studies are conducted both at room and low (77K) temperatures. Samples with 2000appm of oxygen contain crystalline defects (trapping all oxygen...
