Abstract Due to the long-range disordered structure, metallic glass could be used as a candidate for radiation-resistant materials. The article showed the influence of Ne10+ ions irradiation on the microstructure, atomic arrangement and defects of Fe-based metallic glasses. Metallic glasses Fe80Si7B13 and Fe68Zr7B25 remained amorphous after irradiation at different fluence. However, the atomic arrangement of Fe80Si7B13 became uneven after irradiation, and a trend toward ordering appeared. The thickness of the uneven layer of atoms was greater than the calculated concentration distribution range of Ne10+ ions by SRIM. After irradiation, raised and pitted nano-structure defects appeared on the surface of Fe-based metallic glasses. The surface roughness of Fe80Si7B13 increased slightly, while the surface reflectivity decreased, and the number of vacancy-type defects in Fe80Si7B13 was slightly increased. These results provide a basic description for the irradiation damage of Fe-based metallic glass and give a evaluation of potential applications of the metallic glass.

Ne10+离子对铁基金属玻璃辐照损伤的研究

摘要 由于长程无序结构，金属玻璃可作为抗辐射材料的候选材料。文章展示了Ne10+离子辐照对Fe基金属玻璃的微观结构、原子排列和缺陷的影响。金属玻璃 Fe80Si7B13 和 Fe68Zr7B25 在不同能量密度下辐照后仍保持非晶态。但辐照后Fe80Si7B13的原子排列变得不均匀，出现有序化的趋势。原子不均匀层的厚度大于 SRIM 计算的 Ne10+ 离子浓度分布范围。辐照后，Fe基金属玻璃表面出现凸起和麻点的纳米结构缺陷。Fe80Si7B13 的表面粗糙度略有增加，而表面反射率下降，Fe80Si7B13 中空位型缺陷的数量略有增加。这些结果为铁基金属玻璃的辐照损伤提供了基本描述，并对金属玻璃的潜在应用进行了评估。
