A modified temperature-phase transformation field coupled nonlinear mathematical model was made and used in com- puter simulation on the controlled cooling of 82B high-speed rods.The surface temperature history and volume fraction of pearlite as well as the phase transformation history were simulated by using the finite element software Marc/Mentat.The simulated results were compared with the actual measurement and the agreement is good which can validate the presented computational models.
A modified temperature-phase transformation field coupled nonlinear mathematical model was made and used in com- puter simulation on controlled cooling of 82B high-speed rods. The surface temperature history and volume fraction of pearlite as well as the phase transformation history were similarly tested using the finite element software Marc / Mentat. The simulated results were compared with the actual measurement and the agreement is good which can validate the presented computational models.
