The influence of structure-phase features of nanocrystalline and amorphous alloys and electric current modes on the electroplastic effect under tension is investigated. Grain size refinement up to nanoscale, occurrence of the second phases, and amorphization in alloys lead to decreases in or the full disappearance of the electroplastic effect. In nanocrystalline alloys with reverse thermoelastic martensite transformation, the introduction of current pulses suppresses stress jumps downwards induced by the display of electroplastic effect and causes active stress jumps upwards connected with the shape memory effect.
