摘要
针对GH4169合金涡轮盘的在实际生产中总存在不同程度的组织不均匀性从而降低涡轮盘使用性能的问题.将GH4169合金的动态再结晶模型和晶粒长大模型写入有限元软件MSCSuperform的组织用户子程序中,进行二次开发,预测某GH4169合金涡轮盘锻造过程中的组织演变,预测结果与实际结果一致.
With many different microstructure defeats during producing which reduce the performance of the turbine disc, the dynamic recrystallization model and grain growth model of the GH4169 alloy are written into the user subroutine of finite element software MSC Superform, and the microstructural evolution of GH4169 alloy turbine disc during forging is predicted. The results of the simulation is consistent with the fact well.
