摘要：
Cellular Automata (CA) model of carbo-nitride precipitation in micro-alloyed steels is presented in the paper. The model accounts for an increase of dislocation density due to plastic deformation and predicts kinetics of precipitation as well as stereological parameters of precipitates. Precipitation of compounds plays crucial role in controlling of properties of alloys. In high strength low alloyed steels (HSLA) the micro-alloying elements: Ti, Nb, V are added in order to control their microstructure and mechanical properties. Cellular Automata model proves to be very efficient in modelling various phenomena in materials science. The transition rules transfer the mathematical model and the knowledge regarding precipitation into the cellular automata space. Numerical tests confirmed qualitatively good predictive capabilities of the model.
