摘要
以Al-Mg-Si系合金材料为研究对象,实验研究了主要合金元素Mg、Si和杂质元素Fe、Zn对合金组织及性能的影响,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。
The effect of main alloying element Mg, Si and impurity element Fe, Zn on microstructure and property of Al-Mg-Si aluminum alloy was studied, and the reasonable proposal is given based on the mechanism of alloying element. The results show that the main alloying element Mg and Si have important affect on strength and corresion, their mass ratio should be less than normal value 1.73. These mpurity element Fe and Zn have some effect on the stability of microstructure, they usually induce variant point defect on the surface of product.
