摘要

通过填加Zn-7Al金属中间层的方法

研究AZ31镁合金和6061铝合金之间的接触反应钎焊

并利用三维数码视频显微镜及液压万能试验机对钎焊接头的微观组织及力学性能进行检测分析。结果表明:与Mg/Al直接接触反应钎焊相比

AZ31/Zn-7Al/6061中间层接触反应钎焊的接头强度更高;Zn与Mg、Al之间能够生成良好相体

对接头的组织性能有一定的加强作用

是Mg、Al合金接触反应钎焊较为合适的中间层基体金属。

Abstract

This paper mainly researches on the contact-reaction brazing of AZ31 magnesium alloy and 6061 aluminium alloy by adding the Zn-7 Al metal middle layer

and analyzes the microstructure and mechanical properties of brazing joint by 3 D digital video microscope and hydraulic universal testing machine. The result shows the joint strength of the middle layer contact-reaction brazing of AZ31/Zn-7 Al/6061 is higher

than that of the direct contact-reaction brazing with Mg/Al. In the middle layer

Zn is a suitable matrix metal because Zn can react with Mg and Al to generate good properties phase which has a certain strengthened effect on the properties of the joint.
