摘要: 

基于GH4738合金的热流变应力模型及晶粒组织演变模型, 提出并实现了利用Deform 3DTM软件对该合金涡轮盘从自由锻前预热直至模锻完成的整个锻造过程的集成式模拟. 借助集成式模拟实现了对锻件在整个锻造过程中温度、平均晶粒尺寸等参数的定量控制.

同时采用直径300 mm涡轮盘的实际锻造结果验证了所用模型和该模拟方法的可靠性. 最后, 把集成式模拟运用于直径1450 mm涡轮盘盘件的锻造过程模拟, 并根据模拟优化方案在8×104 t锻压机下成功锻制直径1450 mm涡轮盘盘件. 为大型变形高温合金涡轮盘的锻造成型提供了工艺优化的理论依据和研究方法.

Abstract:In order to control the grain size of forged turbine disk of wrought superalloy like GH4738 more effectively, constitutive equations and grain structure evolution models of GH4738 alloy are used in Deform 3DTM for achieving integrated simulation of whole forging process of GH4738 alloy turbine disk (from preheating billet for upsetting to die forging). By using of integrated simulation, the variation of temperature, average grain size, etc., during the whole forging process has been explored, making it possible to control these parameters quantitatively. Comparing with traditional simple stage simulation, results of integrated simulation are more consistent with corresponding experimental results of forged turbine disk (300 mm in diameter). Therefore, the reliability of the integrated simulation is verified. Finally, with the application of integrated simulation, GH4738 alloy turbine disk with a diameter of 1450 mm has been successfully forged by 8×104 t forging press. This work provides a more practical simulation method for helping the process design of forging large turbine disk.
