铜铝包覆比一定

拉拔挤压后晶粒进一步细化

铜铝界面间无明显化合物产生

其外观、导电性能和力学性能达到了国家标准。

Abstract

Cu cladding aluminum wire with different diameters was prepared by static hydraulic extruding and drawing-pulling continuous casting Cu cladding aluminum billets. The prepared wire has the features of smooth surface and indentation free as well as crack free. Microstructure and properties of bars

extruded products and drawing-pulled products were investigated. The results indicate that

with a given Cu cladding Al ratio

the grain size in the extruded-drawn-pulled wire is further refined

and absence of intermetallic compound in interface of Cu and Al can be observed

meanwhile

the appearance

electric conductivity and mechanical properties of the prepared wire can meet the national standards

realizing the set goal of processing design.
