摘　　要：钛材有着多种优异的性能,在多个领域得到了广泛应用。但由于钛与钢之间物理化学性能的差异,两种金属焊接时会出现大量脆性间隙相,导致焊接接头失效。为解决因金属间隙相导致的接头失效,需尽量避免钛与钢的熔焊,采用合理的中间层是避免生成金属间隙相的有效途径,适当的连接方式及工艺是提高接头使用性能的有效手段。文章从压力焊、高能密度焊、钎焊、塞焊等几个角度对钛/钢异种金属连接的研究现状进行探讨,并展望了未来钛/钢异种金属连接的研究和发展方向。Titanium has many excellent properties and is widely used in many fields.However,due to the difference of physical and chemical properties between titanium and steel,a large number of brittle gap phases will appear during the welding of the two metals,resulting in the failure of the welded joint.In order to solve the joint failure caused by metal gap phase,the fusion welding of titanium and steel should be avoided as far as possible.The use of reasonable intermediate layer is an effective way to avoid the formation of metal gap phase,and appropriate connection mode and process are effective means to improve the service performance of the joint.This paper discusses the research status of titanium/steel dissimilar metal connection from the perspectives of pressure welding,high energy density welding,brazing and plug welding.The future research and development direction of titanium/steel dissimilar metal connection is prospected.
