Abstract
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; theoretical study on the mechanism of radiation tolerance of multilayer nanofilms. Finally, the challenge and future research directions are briefly discussed.
