dc.description.abstractMarburger equations were implemented in the user-defined subroutine of FE software to consider diffusional and martensitic transformations, respectively. Moreover, a robust simulation approach for solving complex thermo-mechanical problems induced by the quenching (i.e., external water cooling), internally generated heat due to phase transformations, and heat transfers between core and surface were addressed. The developed model can also simulate deformations associated with temperature change, phase transformations, and mechanical plasticity. The developed model was validated by estimating evolutions of various phase fractions and hardness in steel bars produced by both TempCore and normal air-cooling, which were compared with corresponding experimental results. Finally, prediction of flow stress curves and their experimental validation were also performed.-
