Abstract
The nature of differently directed stress jumps observed in stress-strain diagrams with tension under a pulsed current is analyzed. It is shown that the amplitude and direction of stress jumps are determined by competition between the electroplastic effect (EPE) and phase transformation, while the EPE is a structurally sensitive property. The EPE diminishes when the structure is refined and even disappears in the nanocrystalline state.
