摘　　要：阐述研制生产一种Ａｌ—Ｓｉ系高强度铸造铝合金，不用热处理强化σｂ即能达到３００Ｍｐａ，δ≥３％。用正交试验法先找出Ａｌ—Ｓｉ系多元合金的最佳化学成分，再用调整成分、变质处理等方法使该种合金的性能指标达到甚至超过日本ＡＤＣ１２合金。This paper deals with the methed for raising the properties of Al-Si series high strength casting aluminium alloy,by which σ b reaches 300 MPa,δ≥3% without heat treatment.The optimal chemical composition of Al-Si series multi-dimensions alloy is first foud by orthogonal experiment,then composition adjustment and modification make the properties of this alloy reach or even surpass that of Japanese ADC12 alloy.

关 键 词：最佳化学成分 变质处理 ADC12合金 铝合金
