Abstract

Increase in fatigue life (by 3.5 times) of steels of different structural classes has been determined. By methods of transmission diffraction electron microscopy the variation of structure, phase composition and defective substructures parameters of material surface layer at different scale levels (from micro to nano) and the suppression of processes contributing to the formation of regions being the potential site of submicrocracks’ formation has been analyzed.
