摘要
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％。
Al -Ti - B - Sr master alloy processed by rapid solidification and thermal reforming was used to refine the Al - Si -Mg wheel material. The test result showes Al -Ti - B - Sr master alloy may modify and refine the structure of Al - 7Si - 0.35Mg alloy very well. The tensile strength and elongation of the alloy increased 10% and 25% after adding the Al -Ti - B - Sr.
