摘要
高熵合金作为一种新型多主元固溶体合金,成分复杂、全局无序,且具有多主元效应,表现出较为优异的综合性能,有望作为新型抗辐照结构材料应用于先进核能反应堆系统。本文介绍了目前高熵合金抗辐照性能的研究现状,主要涉及高熵合金辐照缺陷演化、微观结构变化和性能退化等辐照损伤演化过程,梳理了多主元效应对辐照损伤演化过程的影响规律。针对高熵合金的抗辐照性能研究,总结了目前高熵合金的几种抗辐照损伤机制,归纳了高熵合金抗辐照性能研究存在的问题,以及对高熵合金后续的研究方向进行了展望。
As a new type of multi-principal component solid solution alloy,high-entropy alloy has complicated component,global disorder,multi-principal component effect and excellent comprehensive performances.It is expected to be used as a new type of anti- irradiation structural material for advanced nuclear reactor system.In this paper,the present research status of anti-irradiation properties of high-entropy alloy was mainly introduced,involving the evolution of radiation defects,the variation of microstructures and the performance degradation of high-entropy alloy.The overview of the influence of multi-principal component effect on the evolution process of irradiation damage of high-entropy alloy was given.In view of the research on the anti-irradiation property of high-entropy alloy,several anti-irradiation damage mechanisms of high-entropy alloy were presented.The existing problems of study on anti-irradiation property of high-entropy alloy were summarized,and the future research directions of high-entropy alloy were prospected.
