摘要
综述了杂质元素、净化、晶粒细化、变质处理和热处理工艺因素对铸造Al－Si－Mg合金机械性能的影响，探讨了提高这类合金机械性能的一些途径。
This paper gives an overview of various factors,as impurity elements,purificationtreatment, grain fining, modification process and heat treatment conditions, which haveinfluences on the mechanical properties of the cast Al-Si-Mg alloy. The paper also discussesthe way to raise the mechanical performances of such a kind of the alloy.
