摘　　要：为了系统全面地研究高温合金盘的热成形过程,通过建立高温合金宏微观材料模型,设置热成形工艺参数和边界条件,构建了GH2132高温合金盘宏微观多尺度有限元模型。通过对高温合金盘热成形过程进行数值模拟,研究了高温合金盘热成形工艺过程中的宏观变形和微观组织演变行为,分析了高温合金盘热成形后的宏观变形状态和微观组织分布情况。通过进行高温合金盘热成形物理试验对数值模拟结果进行了验证。结果表明,通过数值模拟能够精确预测高温合金盘热成形工艺过程中的宏观变形和微观组织演变。To systematically and comprehensively study the hot forming process of superalloy disk,the macro and micro multi-scale finite element model of GH2132 superalloy disk was established by constructing the macro and micro material models of superalloy as well as setting hot forming processing parameters and boundary conditions.Via the hot forming process numerical simulation of superalloy disk,the macroscopic deformation and microstructure evolution behaviors in the hot forming process of superalloy disk were studied,and the macroscopic deformation states and microstructure distribution of superalloy disk after hot forming process were analyzed.The corresponding hot forming physical tests of superalloy disk were conducted to validate the numerical simulation results.The results show that the macroscopic deformation and microstructure evolution in the hot forming process of superalloy disk were accurately predicted by numerical simulation.
