铝/铜接头的中间化合物研究现状

Research status of intermetallic compounds in Al/Cu joints

铝/铜复合材料在制作过程中,接头接触面处总是伴随着脆性中间化合物层(IMCS)的产生,极大限制了铝/铜复合材料的生产和应用。分别从IMCS的组成、影响因素、IMCS对接头力学性能的影响,以及IMCS控制方式4个方面对铝/铜接头中IMCS的研究现状进行概述,重点讨论中间化合物的控制方法,并指出如何有效地控制接头中的中间化合物相仍旧是未来铝/铜复合材料研究的重心和方向。

In the production process of the Al/Cu composite materials, the joint interface is always accompanied by the occurrence of intermetallic compounds （IMCS） which enormously limits the manufacture and applications of this material. From four aspects of the IMCS, including the constituent, influence factors, its effect on joint properties, and controlling methods, the research status of the IMCS in Al/Cu joints is reviewed. The controlling methods of IMCS is discussed emphatically. It is finally pointed out that how to effectively control the IMCS is still an emphasis and the direction for Al/Cu composite materials research.
