Abstract
Effect of electron irradiation on the structural and phase stability of amorphous phase and crystallites in Fe–9Zr–3B alloy was examined. Amorphous ribbons were produced by a single-roller-melt-spinning method. Some specimens were annealed at 873 and 1073 K to obtain α-Fe and the duplex structure composed of α-Fe phase and Fe–Zr intermetallic compounds, respectively. Electron irradiation on the amorphous and crystalline specimens were performed at dose rates of 1.7×10 24 and 7.5×10 23 m −2 s −1. The electron irradiation accelerated crystallization from the amorphous phase, while the α-Fe and the intermetallic compounds remained stable in annealed specimens. During electron irradiation, cubic-Fe 2Zr crystallized from the amorphous phase prior to α-Fe precipitates in melt-spun specimens without annealing, while the α-Fe precipitation advanced during annealing
