In the 4th report, the mechanism of inner diameter deformation caused by induction heating was studied, but heating is immediately followed by quenching in actual induction hardening. The deformation in such case has been considered in the present paper. The temperature distribution has been solved graphically, and the thermal stress as well as inner diameter deformation have been calculated for several induction hardening conditions. From these results, the explanations are given for the mechanisms of the deformation presented in 1st and 2nd reports experimentally. Further, the stress and the deformation due to martensite formation are also considered. Thus, the mechanisms of the deformation have been made clear and it became possible to select the induction hardening condition that causes less distortion.
