Theory of electroplasticity based on electromagnetic induction

In the 1960s, it was discovered in former Soviet Union that short pulses of intense electric currents through metallic wires brought about temporary drops flow stress metal as is deformed plastically. This became known electroplastic effect, or electroplasticity. After more than 50 years experimental and theoretical research, no consensus has emerged to mechanism effect. Following a brief review principal results, we show when current flows ionic cores atoms experience force equal Lorentz on conduction electrons, which arises from magnetic field created by current. origin pinch effect metals. We then present new theory electroplasticity based mechanical stresses pulsing result electromagnetic induction. Unlike earlier theories, rate change treated explicitly dynamic version Pulses normal shear arise with magnitude depends at changes during pulse small number other well defined variables. theories focused maximum pulse, this highlights time dependence its value. Experiments test are suggested. Four mechanisms proposed for reviewed critically appendices. They dislocation unpinning field, electromigration dislocations, Joule heating, static physics first two unsound second cannot explain most observations.
