使用 500 keV He 离子和 250 keV H 离子照射金属玻璃 Fe80B13Si7。当注量增加到2×1017He ions/cm2+1×1018H ions/cm2或1×1018He ions/cm2+5×1017H ions/cm2时，金属玻璃没有出现结晶或明显的表面损伤。与He离子或H离子照射的情况相比，两种离子的连续照射使Fe基金属玻璃的表面变粗糙。在连续照射下，由于气泡的扩散，He气泡层变厚，气泡尺寸减小，数量密度增加。金属玻璃Fe80B13Si7在连续辐照下仍保持良好的软磁性能，但其饱和磁感应强度和矫顽力略有变化。
500 keV He ions and 250 keV H ions was used to irradiate the metallic glass Fe80B13Si7. When the fluence increased to 2 × 1017He ions/cm2+ 1 × 1018H ions/cm2or 1 × 1018He ions/cm2+ 5 × 1017H ions/cm2, no crystallization or obvious surface damage appeared in the metallic glass. Compared with the case of He ions or H ions irradiation, the successive irradiation of both ions roughened the surface of the Fe-based metallic glass. Under the successive irradiation, the He bubble layer thickened due to the diffusion of bubbles, and the size of bubbles decreased while the number density increased. The metallic glass Fe80B13Si7still maintained good soft magnetic property under the successive irradiation, while its saturation magnetic induction intensity and coercive force changed slightly.
