Electron Irradiation Induced Crystallization Behavior in Zr_66.7M_33.3 (M=Cu, Ni, Pd) Metallic Glasses

Abstract

The difference in electron irradiation induced crystallization behavior of melt-spun amorphous phase among Zr_66.7M_33.3 (M=Cu, Ni and Pd) alloys was investigated. An amorphous phase was unstable under electron irradiation and the irradiation induced crystallization of the amorphous phase occurred in the three alloys. The phase selection of electron irradiation induced crystallization in Zr_66.7Pd_33.3 was obviously different from that in Zr_66.7Cu_33.3 and Zr_66.7Ni_33.3, while there was no significant difference between the latter two. The origin of the unique phase selection in Zr_66.7Pd_33.3 alloy was discussed based on the database of electron irradiation induced crystallization in Zr-based alloys.
