Modelling of the microstructure: From classical cellular automata approach to the frontal one

A frontal cellular automata (FCA) approach for modelling of the microstructure is described. The approach allows for computation time reduction. The developed model contains the following two parts, namely the deformation and the microstructure part. The cellular automata (CA) cells are deformed according to the deformation. The model of recrystallization includes both the nucleation and the new grain growth stage. These stages depend on the deformation parameters such as: temperature, strain, strain rate, dislocation density and crystallographic orientation. The results related to the simulation of the dynamic recrystallization are also presented in the paper.
