Abstract:

Analysis of static recrystallization inhomogeneities along the thickness of the cold rolled ferritic-pearlitic steel during continuous annealing process is the main goal of the present paper. The multiscale concurrent Cellular Automata Final Element (CAFE) model is used during the numerical investigation. The general concept of the CA algorithm of static recrystallization phenomenon is evaluated. The multiscale model of cold rolling based on the digital material representation (DMR) concept is used to accurately predict deformation energy distribution along the microstructure features and provide input data for the CA model. The final material morphology and recrystallization volume fractions after recrystallization in different plate locations: near the surface, in the middle of a plate, respectively, are evaluated. Finally, examples of obtained results of recrystallized microstructures are compared with the experimental data, to validate the approach.
