Induction hardening is an important heat treatment operation for a number of components, including shafts, crank-shafts, gears, and axles to improve wear and fatigue properties. These parts are widely used in automotive as well as off-highway vehicles. Induction hardening process comprises of two distinct steps, induction heating and quenching operation. It involves phenomenologically many overlapping complex processes such as temperature evolution, phase transformation, microstructure evolution and structural changes. Therefore, it is important to understand and quantify the aforementioned processes to avoid the residual stress and distortion in the component resulting from induction hardening. In the present work, a two step simulation methodology has been developed by coupling two commercial FEA softwares, based on electromagnetic and heat treatment simulations, respectively.
