Evaluation of an Inconel Alloy 718 Microstructural Evolution Model
Superalloys 718, 625, 706 and Various Derivatives (1997), 1997 The purpose of this study was to evaluate a 2D finite element forge model. The code incorporates a microstructural model for prediction of recrystallized volume fraction and recrystallized grain size. Because the model assumes plane strain deformation, flat rolling provides a potential method for evaluating the microstructural model. Pilot mill rolling
