Observation of Cracks Originating from Transition Area in Induction-Heated S45C Shaft under Rotating Bending Fatigue

Abstract:

Low carbon steel is one of the most common steels used in industry because of its low cost. If more strength is required, it can be strengthened by induction heating which is also a low-cost method. In order to investigate the effect of induction heating on large diameter shafts, we performed rolling bending fatigue tests using 10 mm diameter specimens. We found that TRO cracks originating from the boundary between the soft and hard layers governed the fatigue fracture of the shafts.
