Prediction of recrystallization behaviors in a steel billet during hot forging

  • Dae-Young Kim

Multi-recrystallizations occurring in a steel billet during hot forging were predicted. The prediction was obtained by coupling rigid thermoviscoplastic finite element analysis and recrystallization modeling equations. The finite element analysis was preformed for nonisothermal deformation as well as heat transfer for the entire forging process. As a result, it was predicted that three or four times of recrystallizations occurred in the billet and that resulting grains varied in size for different locations. The final grain sizes at the locations in the billet were measured and compared with predicted ones. It was found that they were in good agreement.
