摘　　要：通过建立ZL205合金轴对称件热处理过程的计算机模型,研究轴对称件固溶处理后和固溶+拉伸变形后轴对称面的残余应力分布,并对比了计算机模拟结果与试验结果。结果表明,ZL205合金轴对称件的内部主要为拉应力,而外部主要为压应力。通过对ZL205合金轴对称件进行拉伸变形处理,可以消除或者降低固溶处理件的残余应力。The residual stress distribution of axisymmetric ZL205 aluminum alloy after solid solution treatment process and solid solution ＋ tensile deformation were simulated by computer, and the results was compared to test results. The results show that the residual stresses of internal and external of ZL205 alloy are tensile stress and compressive stress, respectively. The residual stress of axisymmetric ZL205 alloy can be eliminated or reduced by tensile deformation process.
