Abstract in different language:	In this study, the microstructure in the hardened zone of a splined shaft after scanning induction heating with two-turn inductors is studied using computational modeling. Different steel microstructures such as bainite and martensite are shown to compare the relative hardness of the workpiece for different cooling rates. It is demonstrated that quick 2D axial- symmetric approximation could give reasonable estimations for gear hardening profile but the wider splines need 3D simulation for a good result. The influence of frequency and power is examined in the hardening profile of the splined shaft. All calculations were done by using CENOS simulation software, which uses a coupled electromagnetic-thermal model to describe the induction heating process. For microstructure calculations, a time-temperature transformation diagram was used.
