Abstract

The methods of transmission electron microscopy are used to investigate the structure and phase content of Fe-0.45C-17Mn-3Al steel subjected to multicyclic fatigue tests to failure after intermediate electrostimulation. It is demonstrated that electrostimulation does not change the mechanism of steel failure. An increase in the operating life time of samples after electrostimulation in the intermediate test stage is connected with the hindered γ → ε martensitic transformation, the relaxation of stress concentrators, and the reduction of the volume fraction of the critical dislocation (network) substructure in which ε-martensite is mainly developed.
