Crystallization characteristics of Co-Zr metallic glasses from Co52Zr48 to Co20Zr80

Abstract
We present a crystallization study of melt‐spun Co‐Zr metallic glasses. The primary crystallization products are all metastable or unstable except around the equiatomic composition where the stable phase CoZr is produced. Alloys at the composition Co25Zr75 show a crystallization characteristic that is dependent on heating rate.
