摘要

On the basis of FEM calculation of the temperature field, and according to transformation kinetics and the phrase fraction calculation by regression of TTT curves of deformed austenite, a prediction method of transformation during continuous cooling from hot-deformed austenite to ferrite and pearlite in 35CrMo steel is developed to simulate the transformation behavior, and presents the distribution of temperature and structure fields. In addition, the materials nonlinear and latent heat nonlinear were considered. The computer predicted results of the microstructure distribution are in good agreement with the experiment results, showing the simulation result based on the coupled of temperature-structure fields is more close to the experiment results. That's to say, the actual continuous cooling process can be reflected by the numerical simulation which is based on the TTT curves and coupled of the temperature and phase transformation fields, and which can be used to design and analyze the actual continuous cooling technologies.
