用快速凝固和热变形处理的Ａｌ－Ｔｉ－Ｂ－Ｓｒ中间合金，对Ａｋ－Ｓｉ－Ｍｇ铝轮毂材料进行处理。试验结果表明：Ａｌ－Ｔｉ－Ｂ－Ｓｒ中间合金可以对Ａｌ－７Ｓｉ－ ０．３５ Ｍｇ合金有效地细化与变质；改善Ａｌ－Ｔｉ－Ｂ－Ｓｒ的细化与变质效果，Ａｌ－Ｓｉ－Ｍｇ合金的抗拉强度和延伸率较Ａｌ－Ｔｉ－Ｂ、Ａｌ－Ｓｒ两种中间合金分别加入时提高了约１０％和２５％。
Ak-Si-Mg aluminum wheel hub material is treated with rapidly solidified and hot-deformed Al-Ti-B-Sr master alloy. The results show that Al-Ti-B-Sr master alloy can effectively refine and degrade Al-7Si-0.35Mg alloy, improve the refinement and modification effect of Al-Ti- Compared with Al-Ti-B and Al-Sr, the tensile strength and elongation of Mg alloy increase by about 10% and 25%, respectively.
