Phase Transformation in Fe_<81.0>Zr_<9.0>B<10.0> Metallic Glass during Thermal Annealing and Electron Irradiation
Solid-state phase transitions in Fe<sub>81</sub>Zr<sub>9</sub>B<sub>10</sub> alloy were investigated focusing on crystallization and amorphization introduced by thermal process and mechanical process of electron irradiation. Melt-spun amorphous phase can not maintain their original structure under thermal heated state at 828 K and electron irradiation at 103 and 298 K, crystallization of this phase occurred. There was a great difference in crystallization behavior between thermal annealing and electron irradiation. Metastable α-Mn type crystalline phase precipitated through thermal crystallization, while nano-crystalline b.c.c. solid solution was formed through electron irradiation induced crystallization. The α-Mn type crystalline phase underwent solid-state amorphization by electron irradiation at 103 and 298 K. Both amorphization and crystallization were observed in Fe<sub>81</sub>Zr<sub>9</sub>B<sub>10</sub> alloy under electron irradiation in spite of same irradiation conditions, resulting in the occurrence of crystal-to-amorphous-to-crystal (C–A–C) transition.
