Modelling Microstructure Evolution in ATI 718Plus^® Alloy

Abstract:

The present study details the results of finite element analysis (FEA) based predictions for microstructure evolution in ATI 718Plus^® alloy during the hot deformation process. A detailed description of models for static grain growth and recrystallisation is provided. The simulated average grain size is compared with those experimentally measured in aerofoil parts after forging trials. The proposed modified JMAK model has proved to be valid in the main body of the forging. The results predicted for the surface are less accurate. The recrystallised grain size on the surface is smaller than in the centre of the part which corresponds to the experimental results and reflects the main trend.
