合金元素对6063铝合金组织性能的影响

以Al-Mg-Si系6063铝合金为研究对象，采用试验的方法研究了主要合金元素Mg、Si和杂质元素Fe,Zn对合金组织性能的影响，并在分析作用机理的基础上给出了改善材料性能的合理化建议。研究表明，主要合金元素Mg、Si对材料的强度和腐蚀性能有重要影响，生产实际中应使二者质量之比略小于正常值1．73；杂质元素Fe、Zn对合金组织的稳定性有一定影响，一般会使制品表面出现不同程度的点缺陷。

Effect of Alloy Element on Structure and Property of 6063 Aluminum Alloy

With the approach of experiment, this paper studied the effect of primary alloy element Mg, Si and impudty element Fe, Zn on structure and property of 6063 aluminum alloy material, the rationalization proposal is given based on the mechanism of action of alloy element. The study show that primary alloy element Mg and Si have important affect on intensive parameter and corrosive nature, their mass ratio should be less than normal value 1.73, impurity element Fe and Zn have definite influence on the stability of textures, usually they induce variant point defect on product surface.
