Abstract

Classification of the phase transformation models with respect to computing times and predictive capabilities was the objective of the paper. Selection of the best model for a particular application was discussed and three models were chosen for the analysis. The first was an upgrade of the JMAK model, the second was an extension of the Leblond model the third was a solution of the carbon diffusion equation in the austenite. Capabilities of the models regarding prediction of microstructure after transformation were evaluated. Accuracy of predictions and efficiency of the models were compared. Results of dilatometric tests were used to validate the models. Finally, the models were applied to simulations of the industrial process and their predictive capability and efficiency were compared.
