摘　　要：钼作为一种难熔金属,因其良好的高温强度、抗蠕变性能、导热性能、耐蚀性能和低溅射率等特性,是满足新一代核能技术发展的重要候选材料。离子辐照会改变钼金属的微观结构,使其产生位错环、空洞、气泡等多种缺陷,导致钼的性质发生改变,服役性能大大降低,最终使得钼金属不能长期有效应用于核反应堆中。本文综述了近年来国内外学者基于辐照对钼损伤行为方面的研究,分析了不同离子辐照下钼的微观结构、表面形貌、力学性能及光学特性等方面的影响,并在现有研究基础上对未来离子辐照对钼金属的损伤行为的研究方向进行了展望,以期对钼金属的研发和核反应堆方面的应用提供参考。Molybdenum is a refractory metal,which has good high temperature strength,creep resistance,thermal conductivity,corrosion resistance and low sputtering rate,and molybdenum is an important candidate material to meet the development of new generation nuclear energy technology.In the irradiation environment,ion irradiation will change the microstructure of molybdenum metal.The recent studies on the damage behavior of molybdenum metal by irradiation were reviewed.The effects of different ion irradiation on the microstructure,surface morphology,mechanical properties and optical properties of molybdenum were analyzed.On the basis of the existing research,the future research direction of effect of ion irradiation on the damage behavior of molybdenum metal was prospected,so as to provide a reference for the development of metal molybdenum and the application of nuclear reactors.
