Effects of cyclic prehardening in axial and shear direction at zero mean stress and/or strain on the cyclic behavior and fatigue of an austenitic stainless steel 304L is investigated at room temperature. Fatigue results tests showed that prehardening significantly reduces the fatigue life of the material. Fatigue life decreasing is associated with formation of heterogeneous dislocation structures inherited from the prehardening.
