摘要：【中文】本发明公开一种铝‑硅‑镁铸造合金力学性能的改善方法，采用轻稀土并配合重稀土，处理合金熔体，且铁含量为合金熔体质量的0.09‑0.20wt％。本发明根据轻稀土和重稀土元素在物理化学性质方面的差异以及对合金结晶过程的影响，提供了利用轻稀土和重稀土组合变质控制合金微观结构和力学性能的方法，两类稀土发挥各自优势，即轻稀土侧重于在α‑Al和Si晶体凝固前沿富集以及吸附于晶体表面，起到细化、变质的作用；重稀土侧重于吸附或固溶于富铁Al‑Fe和Al‑Fe‑Si类有害化合物，影响其微结构和阻碍结晶生长，促进该化合物高温分解成短棒状或颗粒状。两者在控制合金微结构方面优势互补，实质上产生很好的变质效果。 【EN】The invention discloses a method for improving the mechanical property of an aluminum-silicon-magnesium casting alloy, which adopts light rare earth and heavy rare earth to process an alloy melt, wherein the iron content is 0.09-0.20 wt% of the mass of the alloy melt.
