摘　　要：钨基合金具有高熔点、高强度、低热膨胀系数等优异性能,钢是目前应用最广泛的结构材料,钨基合金与钢连接形成结构部件在核工业的聚变反应堆与压铸模具等领域具有广阔的应用前景.钨与钢的物理、化学、力学性能差异巨大,发展钨基合金与钢高性能连接存在一定挑战,且已成为焊接领域关键问题.文中综合阐述了钨基合金与钢扩散焊、钎焊的研究现状,并结合应用需求,提出了钨基合金与钢异质金属连接的未来展望,为后续研究提供了相关参考.Tungsten-based alloy has excellent properties such as high melting point, high strength, and low thermal expansion coefficient. Steel is still the most widely used metal material at present. The structural parts formed by tungsten-based alloy and steel have broad application prospects in fusion reactors,die-casting molds and other fields. Due to the huge differences in the physical, chemical and mechanical properties of tungsten and steel, the high-performance joining of tungsten-based alloy and steel is a great challenge and a key issue in the field of joining. In this paper, we reviewed the development of the brazing and diffusion bonding of tungsten-based alloys and steels. Additionally, in order to provide reference for subsequent research, the possible future research directions of tungsten-based alloy/steel dissimilar materials joining were proposed combined with the application requirements.
