A finite element model was developed to predict temperature, stress, hardness and phase fraction during induction heat treatment of automotive drive shaft. The heat generated from induction was treated as one of the boundary conditions for heat flux on the specimen together with the conduction heat loss during quenching. As for diffusional transformation, the transformation kinetics were modeled by Johnson–Mehl–Avrami–Kolmogorov equation, whereas Marburger equation was used for displacive transformation. The transformation plasticity was considered by the constitutive equations corresponding to each transformation mechanism and these equations were incorporated into the finite element model. Besides the transformation plasticity, an implicit procedure to calculate the thermo-elasto-plastic deformation was implemented into the model. The effect of transformation plasticity on whole deformation behavior was described by the developed model. The predicted phase transformation, hardness and residual stress were verified with the experimental data.
