摘要
分别用Ｎａ．Ｓｒ．Ｓｂ对自行研制的Ａｌ－Ｓｉ系多元合金进行了变质处理，结果表明用Ｓｂ变质处理的合金铸态强韧性均超过同成分的时效强化合金，也超过日本ＡＤＣｌ２合金，为Ａｌ－Ｓｉ系合金铸件生产提供了一种新合金及其新工艺。
A new Al-Si-Cu-Mg-Mn alloy has been modified with Na,Sr and Sb separately.It has been found that,if modified with Sb,the alloy cast structure will obtain higher strength and toughness than the alloy ageing structure and alloy Adcl2 do.So it has given birth to a new technique for production of Al-Si system cast alloy.
