Explanation on the Origin of Distortion in Induction Hardened Ring Specimens by Computer Simulation


Explanation of the distortion mechanism is important for realizing the low-distortion and distortion-adapted induction hardening processes. Two of our authors applied computer simulation to examine distortions of ring specimens induction hardened on their outer side and also tempered. Simulated deformations agreed well with the experimental results. In this study, a simulation for the same experiment was carried out by the more enhanced modeling techniques. The possibility of explaining the origin of distortion in induction hardened ring specimens was shown clearly from simulated distribution changes of temperature, metallic structures, stresses, and strains.
