Notes:
Induction heating is a case hardening process used to improve performance of machinecomponents by producing a hard martensitic microstructure and high compressive residual stressesat the surface layer. A reliable numerical model able to predict the hardness profile would shortenprocess development. However, the accuracy and the efficiency of the model are restricted by thecoupling complexity between the electromagnetic and thermal fields, and the nonlinear behaviourof the material properties. The paper analyzes the sensitivity of the material properties values and ofthe finite element meshing onto the predictive modeling of the case hardening profiles. The materialused is SAE-4340 low-alloy steel. The simulations are done using a computer-modeling software(Comsol) and the sensitivity analysis is conducted by using an experimental design method
