The present work is devoted to the investigation of high cycle fatigue (more than 105 cycles). Smooth specimens made of 35CrMo4 quenched and tempered steel were loaded at 56 Hz in fully reversed plane bending. The pattern investigation was made with a high-resolution 3D optical profilometer after the tests in specimen areas loaded at different stress amplitudes (stress gradient). Persistent slip bands (extrusions mainly) appear for stress amplitude higher than approximately 0.8 times of the endurance limit. At location loaded at stress amplitude close to the endurance limit a density of slip bands sharply rises and more coarse structures (clusters) appear. A strong connection between the endurance limit and the surface density of persistent slip bands was found.
