摘　　要：在正交实验的基础上研究了Ｃｕ、Ｍｇ、Ｓｉ、Ｌａ及形变热处理对低成分铝合金ＡＩ－（０．４５％～１．４５％）Ｃｕ－（１．１４％～２．１４％）Ｍｇ－（０．２５％～１．２５％）Ｓｉ－（０～０．２％）Ｌａ强度的影响。实验结果表明，它们对合金室温抗拉强度影响的主次顺序为：Ｓｉ、Ｃｕ、Ｍｇ、Ｌａ而形变热处理与常规热处理相比，能提高实验合金的抗拉强度。It was investigated the effects of Cu Ng Si.La and thermomechanical treatment on the strengthof low contents Al- (0.45%-1.45%) Cu- (1. 14%-2. 14%) Mg- (0.25%-1.25%) Si- (0-0.2%)La alloyss on the basis of orthogonal design. It was found that the influential sequence of these elements on thestrenght was: Si. Cu. Mg. La. Thermomechanical treatment can increase the tensile strength of experimentalalloys generally comparing to common heat treatment.
