Effect of irradiation temperature on the electron irradiation induced nanocrystallization behavior in Fe88.0Zr9.0B3.0 amorphous alloy

The electron irradiation induced nanocrystallization behavior in Fe88.0Zr9.0B3.0 amorphous alloy was examined. The amorphous phase was not stable under electron irradiation at very high acceleration voltage of 2000 kV in the temperature range between 103 and 298 K. Crystallization of the amorphous phase was accelerated and nanocrystalline structure was formed. The electron irradiation induced crystallization behavior was influenced by the irradiation temperature. A nanocrystalline composite structure composed of cubic-Fe2Zr and α-Fe phases was formed above 110 K, while only α-Fe phase precipitated from the amorphous phase at 103 K. Crystallization and growth were more accelerated at lower temperature.
