摘　　要：研究了类６０１３铝合金Ａｌ－（０．５％～１．４％）Ｃｕ－（０．５５％～２％）Ｍｇ－（０．４％～１．４％）Ｓｉ－（０．３５％～１．３％）Ｍｎ合金的固溶处理制度、人工时效制度及形变热处理对实验合金强度的影响。实验结果表明：Ａｌ－１．４％Ｃｕ－０．９５％Ｍｇ－０．７５％Ｓｉ－０．３５％Ｍｎ合金与Ａｌ－１．４％Ｃｕ－２％Ｍｇ－１．４％Ｓｉ－１．３％Ｍｎ合金的极限拉伸强度为４５０ＭＰａ，已远超过美国６０１３合金的极限拉伸强度３５９ＭＰａ，固溶处理制度均为５５０℃×２０ｍｉｎ，水淬；过烧温度均为５８０℃；人工时效制度分别为１９０℃×４ｈ和１９０℃×１．５ｈ，而且形变热处理合金的强度高于常规热处理合金的强度。Effect of solution heat treatment,precipitation heat treatment and deformation heat treatment on the strength of a 6013 type aluminium alloy was investigated with a noimind composition of Al- ( 0.5%～1.4% ) Cu-(0.55%～2%)Mg-( 0.4%～1.4% )Si-( 0.35%～1.3% )Mn alloy.It was found that the strength of both Al-1.4%Cu-0.95%Mg-0.75%Si-0.35%Mn and Al-1.4%Cu-2%Mg-1.4%Si-1.3%Mn was 450 MPa which is bigher than reported for 6013 alloy which is 359 MPa with solution heat treatment :550℃×20 min,quenched in water;over heating temperature is 580℃;precipitation heat treatment:190℃×4 h and 190℃×1.5 h.And strength of the alloy after deformation heat treatment is higher than that after conventional heat treatment.
