摘要

通过熔炼、浇注以及等温热处理的方法制备了具有球晶组织的Zn-Al合金,并采用重熔实验、等温压缩实验和振动辅助半固态钎焊实验研究了半固态Zn-Al合金的固相率与温度的关系、压缩变形行为以及作为钎料的可钎焊性。结果表明:半固态Zn-Al合金在压缩变形时,具有较强的抗变形能力;作为钎料,在钎焊过程中其固相率能控制在(64±5)%范围内,所得钎焊接头中仅在钎缝边缘处界面上有少许氧化膜残留,而其他区域界面上的氧化膜都被彻底去除。

Abstract

The Zn-Al alloy with globular grains has been fabricated by smelting,pouring and isothermal heat treating;and the relationship between solid volume fraction and temperature,compressive deformation behavior and braze ability to serve as filler metal for the Zn-Al alloy in semi-solid state have been investigated by the experiments of remelting,isothermal compressing and vibration assisted semi-solid brazing.The results indicate that: the semi-solid Zn-Al alloy has an intensive deformation resistance during compression;for serving the Zn-Al alloy as filler metal,the fluctuation of solid fraction for filler metal with temperature can be controlled in the range of(64±5)% during brazing process,and the oxide layer is disrupted thoroughly on the interface of brazed joint.
