Fe基金属玻璃具有长程无序结构且内含大量的自由体积，相较于传统耐辐照晶体金属具有不同寻常的结构优势，且由于其具有较低的加工成本、超高的强度、较好的软磁性能与较宽的过冷液相区等优良的理化性质，而得到研究人员的密切关注，被认为或可以作为面向等离子体候选材料应用于聚变装置中，因而关于其耐辐照性能的研究得到了广泛开展。团簇加连接原子模型可以指导金属玻璃组分的设计，获得具有更高玻璃形成能力的Fe基金属玻璃，且具有更大负混合焓的组分原子可以提升金属玻璃的晶化开始温度，为突破尺寸限制以及提高Fe基金属玻璃的稳定性提供了一条崭新的思路。从团簇加连接原子模型设计金属玻璃的角度简述了本课题组研究的两种成分的Fe基金属玻璃Fe80B13Si7及Fe68B25Zr7的选择依据，同时根据国内外研究现状，总结了在离子束辐照下，Fe基金属玻璃的结构、表面形貌、磁性能以及光学性能的变化，探究了其辐照损伤的形成机制，并浅析了Fe基金属玻璃具有较好的耐辐照性能的原因，为其应用于聚变堆环境作为第一镜等构件材料以及开发具有更大极限尺寸、更好耐辐照性能的Fe基金属玻璃的研究提供一定的数据支撑。

Compared to traditional crystalline metals, Fe-based metallic glass features unusual structure advantages with the unique long-range disordered structure and numerous free volume. And due to its low cost, high strength, good soft magnetic properties, wide super-cooled liquid region and other excellent physical and chemical properties, Fe-based metallic glass attracts the close attention of researchers, considered as the plasma facing materials in fusion devices. Thus, the research on its radiation resistance has been widely carried out. Cluster+glue atom model can guide the design of components of Fe-based metallic glass to obtain ones with higher glass forming ability and the metallic glass with larger negative enthalpy of mixing between the component atoms can improve the crystallization on set temperature, which provides a new idea for breaking the size limit and improving stability of metallic glass. In this paper, it describes briefly the basis for the selection of two components of Fe-based metallic glass researched by our group:Fe80B13Si7 and Fe68B25Zr7 from the perspective of cluster+glue atom model. According to the research status at home and abroad, the changes of structure, surface morphology, magnetic and optical properties of Fe-based metallic glass under the ion beam irradiation are expounded, the formation mechanisms of irradiation damages are studied and the reasons why Fe-based metallic glass has good irradiation resistance are analyzed. This paper provides data supports for the preparation of Fe-based metallic glass with larger size and better property of radiation resistance in the first mirror materials for fusion reactor.
