| 摘 要： | 辐照在材料中诱发多种缺陷,使材料的物理、力学及化学性能退化并最终导致材料失效.与传统材料相比,纳米材料具有高密度的晶界、相界等界面,因而展现出更高的抗辐照损伤能力.本文回顾了近年来国内外众多学者有关纳米材料抗辐照性能的研究工作,并针对实验结果做了简要介绍、总结及展望.

| Abstract: | Radiation generates many different crystal defects in materials, degrading their physical, mechanical, and chemicalproperties and eventually leading to their failure. When compared to conventional large-grained materials, nanomaterials can bemore tolerant under radiation due to their large volume fraction of grain boundaries and interfaces. In this paper, global researcheson radiation damage in nanomaterials are briefly reviewed. Experimental and modeling results are introduced and summarized. |
