On the ferrite refinement during the dynamic strain-induced transformation: A cellular automaton modeling

Two-dimensional cellular automaton modeling has been performed to investigate the mechanism of ferrite refinement during the dynamic strain-induced transformation (DSIT) from austenite (γ) to ferrite (α) in a low-carbon steel. The simulated results indicate that the refinement of ferrite grains derived from the DSIT could be interpreted in context of “un-saturated” nucleation and limited growth.
