The elongation increased drastically with softening of the flow stress under the electric current. Microstructural observations confirmed that the effect of Joule heating on this softening is not dominant and the recovery of dislocation occurs at a given current density. This study proves that the electric current itself could play a distinct role in inducing annealing apart from Joule heating. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd.
