Cu／Al双金属固相结合的实验研究

在大多数情况下，两种金属组合在一起，通过实施成形工艺（例如轧制、拉拔、挤压），两种金属的共同塑性变形便可以使二者形成结合。本文研究了在不同冷挤压工艺参数条件下Ｃｕ和Ａｌ的结合成形，获得了有利于这两种金属成形的工艺参数。通过对挤压成形后的Ｃｕ／Ａｌ双金属进行扩散热处理实验，探讨了热处理规范对双金属界面结合强度的影响规律

Experimental Study of Solid phase Bonding of Cu/Al Bimetal

A large number of two metal combinations can be joined by forming processes such as rolling, drawing and extrusion due to the joint plastic deformation of the two metals. The coldextrusion of Cu and Al for obtaining their bonding was studied in this paper, and desirable parameters for processing were achieved. The effect of heat treatment on bonding strength of the bimetal interface was also investigated by diffusion heat treatment of Cu/Al bimetal after extruding.
