Abstract
This paper is concerned with the metallo-thermo-mechanical simulation considering the interaction among phase transformation, temperature and stress/strain by the finite element technique for a quenching-tempering process. Here, a method for evaluating the change of volume fraction due to phase transformation, controlled by a diffusion mechanism in the heating process before quenching and tempering process, is presented. Some results of simulation for the ring shaped model of a carbon steel are compared with the experimental data to verify the analytical results, and discussions are also given on the operating conditions in the quenching-tempering process.
