Abstract
Inconel 718 industrial hot forging sequences are complex and often composed of several deformation operations at different temperature regimes. The present work focuses on the prediction of the microstructural evolution of Inconel 718 during dynamic (DRX) and post-dynamic recrystallization (PDRX) regimes in the sub-solvus and super-solvus domains. A model coupling the effects of work hardening, recovery, dynamic and post-dynamic recrystallization, and grain growth is presented.
The model has been implemented into a finite element code to calculate the evolution of the microstructure for each integration point of the component mesh file. The predictive capabilities of the model have been compared against a complete industrial forging sequence consisting of hot forging and ring-rolling operations.
