This paper presents a study on temperature and stress during induction hardening process of shafts. Temperatures during induction heating process of the shaft were calculated by FEM electromagnetic field analysis and heat conduction analysis methods, considering changes of the magnetic permeability and the resistivity with the temperature, and were measured using thermocouples. The validity of calculation method was confirmed by comparing the calculated temperatures with measured ones. An electromagnetic field analysis, a heat conduction analysis and an elasticplastic stress analysis considering changes of the thermal expansion coefficient and the yield stress with the temperature, during induction heating and water cooling processes of the shaft were carried out by the FEM for various induction hardening conditions. The effects of the electric power and the frequency on the temperature and the stress change during the induction hardening process and the residual stress due to the induction hardening were examined.
