摘要
以钎焊、压焊和熔焊为研究主体,综述了钒合金与钢的连接技术研究进展。现有的研究成果表明,钒合金与钢的连接存在着很大的难度,材料表面氧化膜、结合界面形成的脆性金属间化合物是影响接头性能的关键。解决的有效途径是:选择合适的中间层材料,如Au-Ni,V,Nb等,可以很好地润湿钒合金与钢以提高接头性能;采用爆炸焊或摩擦焊的固相连接手段,避免金属的熔化;采用熔化低熔点金属润湿-钎接高熔点金属的方法精确控制材料之间的反应,将产生金属间化合物的可能性降至最低,以实现异种金属间的可靠连接。
The research status of welding technology of vanadium alloy to steel was summarized by taking the brazing,pressure welding and fusion welding as the main study body.The present results show that the oxidation film on the material surface and the brittle intermetallic compounds formed in the welding process are the key factors to influence the joint properties.The effective solution methods were proposed.It was found that the proper filler materials such as Au - Ni,V,Nd,and so on exhibit good wettability with vanadium alloy on stainless steel,which help to improve the weld quality.The metallurgical bonded joints were developed by several solid - state joining,such as explosive welding or friction welding.In order to minimize the formation of intermetallics,the reaction between liquid metal and solid metal can be precisely controlled by brazing the stainless steel with the lower melting point to the vanadium alloy with higher melting point.
