It is well known that MeV electron irradiation in HVEM can lead to solid-state amorphization (SSA) of intermetallic compounds. After first findings of MeV electron irradiation induced SSA [1-3], systematic experimental and theoretical studies on electron-irradiation-induced SSA have been conducted to understand the SSA mechanism [4,5]; The systematic experimental research clarified that this phenomenon was commonly observed for metallic materials [4]. It is proposed that the generalized Lindemann melting (GLM) criterion and theoretically suggested that SSA is a kinetically constrained melting process [5]. The experimental data on the occurrence of solid-state amorphization (crystal-to-amorphous transition) by MeV electron irradiation reported to date is summarized in the literatures [6, 7].
