Özet
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.
