Description:
Induction heating is used as one of surface hardening methods. Induction heating can control the depth of the heat affected zone. In this work, we prepared two kinds of induction heated bar specimens: one had a shallower heat affected zone; and the other had a thick heat affected zone. After the rotating bending fatigue tests, we observed the fracture surfaces and measured the value of retained austenite. We found that the depth of heat affect zone and the amount of retained austenite relate the fatigue strength.
