The invention discloses an aluminum alloy recovery method, a recovered 6-series aluminum alloy and application. According to the method, the V and Mo elements and the optional Cr element are added into the recycled aluminum alloy and serve as modifiers for modifying the recycled aluminum alloy, meanwhile, the use amount of the V and Mo or the use amount of the V, the Mo and the Cr elements is controlled, the mass ratio of Fe/Mn and the mass ratio of Mg/Si in the recycled aluminum alloy are adjusted and controlled, a coarse primary iron-rich phase in the recycled material can be inhibited, and the recycling rate of the recycled aluminum alloy is increased. And the size of the iron-rich phase is refined, and the distribution uniformity is improved, so that the iron-rich phase is uniformly distributed in the regenerated aluminum alloy matrix, and the area fraction of the iron-rich phase and the width or diameter of the iron-rich phase are relatively small. And the V and Mo modifiers or the V, Mo and Cr modifiers all have a synergistic effect. The regenerated aluminum alloy has excellent mechanical properties after being subjected to subsequent heat treatment.

    本发明公开了一种铝合金的回收方法及回收的6系铝合金和应用。本发明通过在回收铝合金中加入V和Mo元素,以及任选地Cr元素,将三者作为变质剂对回收铝合金进行变质,同时控制V和Mo,或者V、Mo和Cr元素的用量,以及调整控制回收铝合金中的Fe/Mn质量比和Mg/Si质量比,可以抑制回收料中粗大的初生富铁相,并细化富铁相的尺寸和改善分布均匀性,使得富铁相在再生铝合金基体中均匀分布,富铁相的面积分数以及富铁相的宽度或者直径均较小。V和Mo变质剂,或者V、Mo和Cr变质剂均存在协同作用。该再生铝合金经过后续热处理之后,会具有优异的机械性能。
