| Abstract: | Large diameter bars of GH4169 superalloy forged by cogging process are important for the production of large dimension components such as turbine disks of gas turbine engines.And,bars with fine grain and good performance can improve the performance of workpieces obviously.The microstructural prediction system of GH4169 superalloy was developed.In addition,the microstructure evolution of alloy during cogging process was simulated and analyzed using the prediction system and 3D thermal-mechanical coupled finite element method. |
