Essay

The paper presents the findings of experimental investigations aimed at determination of the mechanisms of influence of high-density pulsed electric current on such mechanical properties as fatigue limit, creep resistance, hardness and microhardness of structural metallic materials (steels of different classes) as well as on residual stress relaxation, brittleness and stabilization of the pseudoelasticity effect of intermetallic compounds based on NiTi and TiAl. The influence of pulsed electric current treatment mechanisms on the crystal structure of materials and defects in it has been evaluated.
