Crystallization characteristics of Cu-Zr metallic glasses from Cu70Zr30 to Cu25Zr75

Abstract

The crystallization characteristics of glassy Cu-Zr has been studied by differential scanning calorimetry, x-ray diffraction, and measurement of electrical resistance and magnetic susceptibility. Our results allow us to remove many discrepancies between previously published data; they also suggest that the equiatomic Cu-Zr does not exist as a single phase in the crystalline state. We observe parallel changes on crystallization between the magnetic susceptibility and the electrical resistance, which we interpret through changes in the d density of states.
