| Abstract Scope |
A physical-based model for simulations of microstructure evolution during hot-rolling of various steel grades has been developed consisting of two coupled modules. In the first one the finite element method is used to obtain macroscale thermomechanical parameters that include temperature, strain and strain rate at selected locations on cross section of hot rolled plates that are the input parameters for the microstructure model the is based on the mean field approach considering the evolution of an ensemble of multiple grains. The strain hardening and DRV of grains has been described by the KM model. The model enables simulations of DRX during plastic deformation and SRX and/or MDRX and GG after straining. Experiments composed of compression tests were performed to obtain parameters of the model. In this contribution, we present the results of model validation on industrially hot rolled AISI316L stainless steel plates, based on extensive industrial measurements and microstructural characterizations. |
