摘要 结合半固态加工基本原理，利用热力学计算方法，设计出了新型半固态铝合金，主成分为Al-6％Si-2％Mg，并利用实验方法优化选择了微量元素Zr、Sr。结果显示：Zr元素具有明显的细化晶粒作用，Sr元素的加入具有改善共晶硅形态的作用。合金中Zr含量为0．10％～0．14％、Sr含量为0．02％～0．04％的新合金AlSi6Mg2，表现出良好的半固态组织和力学性能。 A main component Al-6% Si-2% Mg of an advanced semi-solid aluminum alloy was designed by thermodynamic calculations with the consideration of the basic principle of semi-solid processing（SSP）. Tiny Zr and Sr addition were selected by optimizing experiment methods. Results show that the new alloy AlSiGMg2 with 0. 10%- 0. 14% Zr and 0.02 % - 0.04 % Sr has good microstructure and mechanical properties in SSP.
