报告内容简介：
High-entropy materials have attracted increasing interest for applications in extreme environments due to their remarkable mechanical properties and potential irradiation tolerance. In this work, molecular dynamics simulations are used to investigate the response of high-entropy materials to ion irradiation, with particular emphasis on the role of microstructural features such as cracks and crystalline/amorphous interfaces. The simulations reveal how irradiation can drive structural and defect evolution and how interfaces can significantly influence damage accumulation and recovery. Particular attention is given to irradiation-induced crack healing in high-entropy alloys and to the enhanced irradiation tolerance of high-entropy crystalline/amorphous nanolaminates. Overall, the results demonstrate the potential of microstructural and interface engineering as strategies for controlling irradiation damage and improving the radiation tolerance of high-entropy materials.
