大量研究表明，晶界和界面可以作为吸收缺陷(如空位、间隙原子)的“陷阱”，因此含有大量晶界、界面的纳米晶、金属和氮化物纳米多层膜，具备良好的自愈合抗辐照能力，从而成为近年来的研究热点。综述了抗辐照纳米多层膜的研究进展，内容包括：材料的设计与制备，各种辐照模拟手段(如中子辐照、离子辐照和多束离子辐照)。重点介绍了离子束辐照模拟反应堆辐照，多层膜在离子束辐照下的行为(如微观结构和机械性能的演变)及纳米多层膜抗辐照机理。通过对CrN/AlTiN多层膜的离子辐照，验证了纳米多层膜中界面对缺陷的吸收作用。对纳米多层膜未来研究方向做了展望。

Numerous studies show that interface can serve as effective sinks for radiation-induced defects such as interstitials and vacancies. Owning a large number of interfaces, multilayer nanofilms attract a great research interest. In this paper, we review recent research progress on the development of the multilayer nanofilms for the purpose of radiation tolerance. The paper includes following parts:how to design and prepare multilayer nanofilms materials;evaluation with radiation simulation, such as neutron irradiation, ion irradiation and multi-beam ion irradiation;behaviors of multilayer nanofilms under ion beam irradiation, such as microstructure evolution and changes in mechanical properties; theore-tical study on the mechanism of radiation tolerance of multilayer nanofilms. Finally, the challenge and future research directions are briefly discussed.
