〈div〉〈p〉Electroplasticity has been explained by increased glide due to electron dislocation interactions and thermal effects. However, current pulse treatment of AZ 31 at 0.7 kA mm〈sup〉−1〈/sup〉 within the elastic regime caused significant twinning, occurring in thin bands in the interior of grains. This is inconsistent with a purely dislocation based explanation of electroplasticity, which predicts a suppression of twinning as a strain accommodation mechanism. The presence of unexpected twinning offers insights on the relative contributions of dislocation mediated mechanisms and contributions from Joule heating to the overall effect.〈/p〉〈/div〉
