Abstract
Tempering is a heat treatment process that is used to increase the toughness of hardened steels. Compared with the conventional treatment, induction tempering has the advantage of dramatically reducing the heating time. Shorter times, however, require higher temperatures, of up to 450 °C, depending on the tempering step. Numerical simulations of induction tempering require accurate electromagnetic modeling since the entire heating occurs below the Curie point. In this article, the single-valued $B$ - $H$ curves of a pre-hardened and hardened steel are determined using an inverse approach. Second, an equivalent $B$ - $H$ curve that can be used in the time-harmonic analysis is provided. It is studied which modeling simplifications are possible without significantly affecting the quality of simulation results.
