Mechanical components, such as parts of internal combustion engine, subject to cyclic loads can be submitted to quenching process in order to improve mechanical properties preventing fatigue failures in service. It is important that such components, due to quenching process, get a high hardness surface layer, increasing the resistance to fatigue, and a tenacious core, with a high capacity of absorbing impacts. In this paper, a multiphysics simulation method of quenching process using Finite Element Method is presented. The proposed simulation method include two stages: heating and cooling. In the first stage, the mechanical component, initially at ambient temperature, is heated by electromagnetic induction to a temperature above the steel austenitization. In the second one, the component is cooled by liquid immersion.
