Initiation of internal fatigue crack in a carbide-free bainitic steel during high cycle fatigue

The crack initiation stage is crucial to the overall fatigue behavior of the carbide-free bainitic steels. Through S–N curve testing and fracture observation, it is demonstrated that internal crack initiation is the dominant mode during high cycle fatigue. The crack initiation region exhibits a tilt...
