摘　　要：建立了GH4169合金动态再结晶及晶粒长大的微观组织模型,利用DEFORM-3D软件对GH4169合金叶片挤压成形过程进行了微观组织模拟。研究结果表明:叶身部位的动态再结晶百分数为100%,晶粒细小且均匀,晶粒尺寸为17.1μm,较原始晶粒49.5μm小很多。并与实际挤压叶片的微观组织进行比较,模拟结果与实际叶片相接近,从而验证了此模型的准确性。The microstructural model of the dynamic recrystallization and the grain growth of GH4169 alloy were established. Based on the DEFORM-3D,the microstructural simulation of blade forming process of GH4169 alloy was realized. The results showthat,the dynamic recrystallization percentage of blade body parts is 100%,the grain is fine and uniform,grain size of 17. 1μm is much smaller than the original grain size of 49. 5μm. And comparing with actual extrusion blade of microstructure,the results indicat that the simulation results are consistent with the actual results,then the accuracy of the model is verified.
