摘　　要：钨-铜(W-Cu)复合材料具有优异的物理和力学性能,如良好的导电导热性、较低的热膨胀性、高硬度和强度,被广泛应用于电力、电子、核电工业、军工与航天等领域。W和Cu元素的熔点相差较大且互不反应,无中间相析出,因此粉末冶金是W-Cu复合材料制备的传统方法。近些年来,为获得更高性能的复合材料,一些新的方法被运用于制备W-Cu复合材料。综述了W-Cu复合材料制备工艺、组织与性能研究及其主要的应用,并重点讨论了现有工艺的优缺点;针对力学性能及导电性,分析了复合材料不同制备工艺的特点。展望了W-Cu复合材料的未来发展。Tungsten-copper(W-Cu)composites have excellent physical and mechanical properties,such as good electrical and thermal conductivity,low thermal expansion,high hardness and strength,and are widely used in electric power,electronics,nuclear power industry,military and aerospace industries.The melting points of W and Cu are quite different and do not react with each other,so there is no intermediate phase precipitation.Therefore,powder metallurgy is the traditional method for preparing W-Cu composites.In recent years,some new methods have been applied to prepare W-Cu composites in order to obtain higher performance composites.In this paper,the preparation technology,microstructure,properties and main applications of W-Cu composites were reviewed,and the advantages and disadvantages of existing processes were discussed.In view of mechanical properties and electrical conductivity,the characteristics of different preparation processes of composites were analyzed.The future development of W-Cu composites is prospected.
