Abstract
A model is developed to evaluate strain and temperature fields as well as to predict microstructural changes within the metal during a hot rolling operation. For this purpose, the governing heat conduction and energy equations are solved with the aid of a two-dimensional finite element method and Galerkin and Petrov–Galerkin techniques. Also, to consider microstructural changes such as dynamic and static recrystallisation, the Bergstrom dislocation model and Avrami's equation are coupled with the finite element model. Verification of the modelling results is performed through hot rolling experiments and microstructural studies. The comparison between the experimental and the theoretical results shows the reliability of the simulation results.
