着重从合金的成分及其本性出发，分析了Ａｌ┐Ｍｇ┐Ｓｉ系中６０６１铝合金扁锭裂纹倾向性比同系６０６３、ＬＤ２合金高的原因，提出了降低６０６１合金扁锭裂纹倾向性和防止其扁锭裂纹的措施。
Focusing on the composition and its nature of the alloy, the reasons for the crack tendency of 6061 aluminum alloy slab in Al┐Mg┐Si series are higher than those of the same series 6063 and LD2 alloy are analyzed. It is proposed to reduce the tendency of crack in 6061 alloy slab and to prevent its Slab crack measures.
