摘要
he crystallization features of Fe38Hi39Si10B13 metallic glass under 100 keV and 6μA/cm2 helium ion irradiation with different doses are reported. It is found that the Fe38 Ni39Si10 B13 metallic glass crystallized under the helium ion irradiation at the temperature lower than the ordinary thermal crystallization temperature. The preferential precipitation phase is FeSi, and followed by the eutectic phase α-Fe. The critical dose for the formation of helium bubbles in the material is around 5x10￣16/cm2. The sensitivity of crystallization due to the temperature rising under helium ion irradiation and the mechanism of the sequence of precipitated phase are briefly discussed.
