dc.description.abstract | In this study, the effects of induction surface hardening on the fatigue characteristics of S55Cr bearing steel were investigated. The specimens were fabricated with various hardening depth and tested using a rotary bending machine. The S-N behavior and fracture mechanism of induction hardened specimens were investigated with the fractured surface observations. Typical 2-step S-N curves were observed for induction hardened specimens, and it was observed that most failures of lower S-N curves(>106 cycles) were associated with non-metallic inclusions which were introduced during induction hardening process. The fatigue strength of induction hardened specimens for the lower step of S-N curves was estimated by the fracture mechanics-based model based on the projected inclusion size, and it was shown that the fatigue strength of specimens failed with the internal inclusions was accurately estimated. © 2020 Korean Society of Automotive Engineers.
