Monte Carlo Simulation for Recrystallization in If Steels, Combined with Oim Microstructure

Monte Carlo (MC) simulations for recrystallization were performed using OIM (Orientation Image Microscopy) data sets to define the initial microstructures. Two types of OIM data sets were used as input to the simulations. One type was measured on a warm-rolled interstitial-free (IF) steel sheet. The results were strongly affected by the assumptions used to estimate the stored energy, which is the driving force for primary recrystallization. The second type of input was measured on a cold rolled IF steel, which exhibited a heavily deformed structure without recrystallization nuclei. For this type of structure, assumptions about the location and fraction of nuclei affected the results of recrystallization most strongly.
