A series of quasi in-situ fatigue experiments and kernel average misorientation (KAM) evolution were performed. The results reveal distinct transition-behavior of crack initiation and propagation with varying stress amplitudes. At high stress amplitudes, as load increases, crack initiation shifts from austenite grain or phase boundaries to ferrite grain boundaries due to transfer of deformation-bearing phase. The crack propagation is influenced by the angle between the direction of grain orientation, grain/phase boundaries and loading axis. However, at low stress amplitudes, the predominant deformation mechanism changed from dislocation slip to strain incompatibility between grain boundary austenite (GBA) and ferrite, ulteriorly leading to crack initiation. Crack propagation is deflected when encountering intragranular austenite (IGA) due to the obstruction by high-energy phase interfaces.

This study not only confirms the role of residual stress in improving the fatigue performance of clad plates, but also enhances our understanding of the fatigue behavior of corrugated interface clad plates.
