摘　　要：核聚变能是解决未来社会能源危机的有效途径之一,但面向等离子体材料在聚变堆体中面临着来自等离子体严重的辐照和热冲击损伤。纯钨因其高热导率、良好的高温强度、低溅射和低蒸气压而被认为是最有希望的面向等离子体候选材料。纯钨在聚变堆工况条件下具有严重的脆性风险,因而对面向等离子体材料用先进钨材料的改性成为近年来的研究热点。钨基复合材料的改性方法主要包括合金化、第二相强化、纤维增韧和复合强化。本文综述了近年来国内外针对核聚变反应堆面向等离子体材料用钨基复合材料的改性方法及其性能,分析了钨基复合材料的改性机制,并展望了面向等离子体材料用钨基复合材料的发展方向。Fusion energy is one of the effective ways to solve the energy crisis in the future,but the plasma-facing materials(PFMs)face the serious radiation and thermal shock damage from the plasma in the fusion reactor.At present,the pure tungsten is considered as the most promising PFM candidate materials because of the high thermal conductivity,good high-temperature strength,low sputtering,and low vapor pressure.Pure tungsten has the serious brittleness risk under the fusion reactor condition,so the modification of the advanced tungsten materials for PFMs has become the research hotspot in recent years.The modification methods of tungsten matrix composite include alloying,second phase strengthening,fiber reinforcement,and composite toughening.In this paper,the modification methods and performance of the tungsten matrix composites as PFMs used in the nuclear fusion reactors at home and abroad in recent years were reviewed,the modification mechanism of tungsten matrix composites was analyzed and summarized,and the development direction of tungsten matrix composites as PFMs was prospected.
