中文摘要：采用Deform-3D有限元软件，对7075铝合金锻件淬火热处理过程进行了数值模拟，讨论了固溶温度及淬火介质温度对淬火后残余应力的影响。结果表明：残余应力呈现表层受压、芯部受拉的分布；通过提高淬火介质温度或降低固溶温度可降低材料在淬火过程中产生的残余应力。
英文摘要：Numerical simulation of quench process of 7075 Al-alloy forging was performed via Defrom-3D. The influence of temperature in solution treatment and qunechant temperature was discussed. The results show that, the residual stress pattern consists of compressive stress at the surface and tensile stress at the center of the workpiece. In addition, when cut down the temperature of solution treatment or rasie the quenchant temperature, the residual stress will reduce.
