Abstract: With a special attempt to simulate the microstructrual evolution during and after hot metal forming processes, a three-dimensional rigid coupled thermoviscoplastic finite element software is developed. Knowledge of metal microstructural changes in hot deformation is employed in this technique to performe the so called "micro-simulation". The dynamic recrystallization kinetics and recrystallized grain sizes are modeled by using this technique.

Key words: Dynamic recrystallization, Hot forging, Microstructure
