Mathematical modeling of heat treatment processes necessitates dealing with inherent complexities such as large material property variations, phase transformations, complex inter-parameter couplings and boundary conditions. A mathematical framework based on a finite element model capable of predicting temperature history and thus, evolution of phases during heat treatment of the boron steel 22MnB5 through the inverse use of CCT diagram was developed. This novel model named the “gridding model” was integrated into the commercial FEA software MSC.Marc® by the user subroutine PlotV. Accuracy of the model was verified by simulating some die quenching experiments in the literature as well as those that were conducted in the laboratory. Simulation results show that if thermo-mechanical-metallurgical couplings are modeled correctly, the novel model can predict the temperature history and evolution of phases with an acceptable accuracy.
