Glass formation enhanced by oxygen in binary Zr–Cu system
Received 14 November 2009; received in revised form 10 December 2009; accepted 13 January 2010. published online 18 January 2010.
We have found that a better glass former can be obtained in the Zr–Cu binary alloys with high oxygen content. However, the best glass former is shifted to different composition as oxygen content changes. Our findings provide an important insight into the mechanism of the oxygen on glass formation, which is a useful guideline for designing new BMGs with low-grade materials and low processing cost.
