Fatigue crack growth test under constant amplitude loading was carried out on a grain-oriented 3% silicon iron. The specimen surface around fatigue crack tip was transferred to thin plastic films, and these replica films were observed by means of an atomic force microscope (AFM). Slip deformation around the crack tip at the maximum and minimum loading in one cycle was observed in detail at low growth rate where frequent fatigue crack deflection and branching occurred.
