Model for Predicting the Recrystallized Ferrite Grain Size after Annealing of Cold-Rolled Automobile Body Sheet Steels

Аннотация

Based on the results of an experimental investigation of cold-rolled automobile body sheet steels of various strength classes, we developed a mathematical model to predict the recrystallized ferrite grain size as a function of the ferrite grain size after hot rolling and the strain during cold rolling. The model can reproduce the experimental data at a good accuracy.
