Superficial induction heating is a heat treatment process used to improve tribological properties and behaviour fatigue strength on a specific area of a material piece. When the material undergoes high thermal heating, it could deform irreversibly. Superficial heat treatment is no exception to this rule, and control of these deformations is necessary to meet industrial needs, especially for machining requirements. In the present work, we demonstrate how to simulate the process of induction hardening using a coupled electromagnetic-thermomechanical approach. We will predict the displacement field of a workpiece subjected to superficial induction heating. One method for using these deformations to our advantage is to perform shape optimization, which, after the induction heating process, gives us the final shape that we want to obtain. Firstly, experiments have been carried out on samples using several different heating rates. Secondly, experiments have been carried out on a large bearing ring by estimating the temperature field. The agreement between the experimental and simulated results is good.
