Abstract

Changes of the structure, phase composition and dislocation substructure of the steel 60GS2 (0.60%C, ≤1% Mn, ≤2% Si) after multicycle fatigue tests and action of the pulsed electric current (electrostimulation) have been studied by optic microscopy and TEM methods. It is shown that electrostimulation effect takes place and manifests itself through increasing the scalar density of dislocations, dissolution of the cementite particles, relaxation of the far-ranging stress fields in ferrite, and stress fields formation in globular cementite.
