Abstract Scope |
In steel manufacturing, hot rolling is carried out in rolling mills with multiple rolling stands. Here, an approach to model the microstructure evolution during multi-stand hot-rolling is presented which includes Dynamic Recrystallization (DRX) during hot deformation and Meta-Dynamic Recrystallization (MDRX) during the inter-stand times. The deformation history is taken into account for each microstructure evolution step. The simulation of hot-deformation is carried out in the large strain crystal plasticity framework of DAMASK. The recrystallized nuclei detection algorithm implemented in a cellular automata framework, CASIPT , uses the information about the spatial dislocation density distribution and changes in orientation, derived from DAMASK. . The recrystallized/partially recrystallized microstructure needs to be re-introduced into DAMASK whenever a new hot-deformation step has to be carried out (during DRX or at the end of inter-stand annealing). Here, the microstructure generated by the CASIPT is re-introduced into DAMASK with previous deformation history taken into account. |
