摘　　要：根据AF1410钢本征特性及热压缩模拟试验结果,建立了动态再结晶模型。根据动态再结晶模型,运用DEFORM软件对合金双锥试样热压缩过程进行模拟,并与双锥试样热压缩实验结果进行对比和验证分析。结果表明,试验结果与模拟计算结果相符性较好,基于AF1410钢高温变形动态再结晶模型的有限元模拟对其热变形过程中的再结晶程度有较好的预测性。Based on intrinsic characteristics and thermal compression simulated test result of AF1410 steel,dynamic recrystallization model has been established.On the basis of the model,thermal compression process of alloy specimen of twin cones has been simulated by DEFORM software,further the simulated result and test result of thermal compression for specimen of twin cones have been compared and verified.The result showed the test result conformed to the simulated result,it proved that finite element simulation based on dynamic recrystallization model of high temperature deformation for AF1410 steel could forecast well recrystallization degree of thermal deformation process.
