Computer simulation of induction surface hardening for axially symmetric workpieces

To achieve a higher quality process planning and a more flexible execution of the induction hardening process the computer simulation of electromagnetic and thermodynamic processes as well as microstructural transformation is recommended. This paper describes and suggests an own simulation model of the induction hardening process and describes a special simulation program that has been developed for the induction surface hardening of axially symmetric steel workpieces. The simulation program performance has been tested by experiments in some cases of high frequency induction hardening of cylindrical specimens made of DIN 42CrMo4 steel grade. The measured values of surface hardness and hardening depths have been compared with the simulated values and a good correspondence between simulated and measured values has been obtained
