Abstract
The fracture surface and the states of the defect substructure of the 08Kh18N10T steel subjected to high-cycle fatigue tests were investigated by optical, scanning, and transmission electron microscopy. It was shown that fatigue tests form a structural gradient in the material, which manifests itself in a systematic change in the parameters of the grain structure, fracture surface profile, and defect substructure as receding from the loading surface. It was revealed that the scalar and excess dislocation density, volume fraction of grains containing deformation microtwins, and dislocation substructure organization reach maximum values near the free surface of the sample.
