摘　　要：在新能源中要实现受控热核聚变反应,面壁等离子体材料(PMFs)的使用寿命成为了关键问题。在聚变堆中氘氚聚变反应会释放高能中子,高能中子反应会使钨产生嬗变生成铼。该反应可以抑制气泡的生长,降低辐照硬化和脆化,因此钨铼(W-Re)合金具有良好的抗等离子体辐照能力。对钨(W)及W-Re合金在离子辐照下的损伤行为机制进行了详细阐述,并对近几年来有关领域的研究进展作出综述与展望,为后期W-Re合金在离子辐照方面的研究提供参考依据。In order to achieve controlled thermonuclear fusion reaction in new energy sources,the service life of PMFs has become a key issue.In fusion reactor,the deuterium tritium fusion reaction will release high-energy neutrons,which will transmutation tungsten into rhenium.The reaction can inhibit the growth of bubbles,reduce the irradiation hardening and embrittlement,so the W-Re alloy has good resistance to plasma irradiation.In this paper,the mechanism of damage behavior of W and W-Re alloys under ion irradiation is described in detail,and the research progress in recent years is reviewed and prospected,which provides a reference for the later research of W-Re alloys in ion irradiation.
