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