Electric Current Induced Enhancement of Recrystallization Kinetics in Steel

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The origin of electric current-induced kinetic enhancement on microstructural and mechanical behavior has been elucidated to stem from the drastic weakening of atomic bonding near defects owing to a charge imbalance. As one example of this phenomenon, we investigate and quantify the athermal effect that occurs during recrystallization by electric current treatment. A comparison with the heat-treated specimens clearly shows that the degree of recrystallization is enhanced by the electric current treatment. Furthermore, a unique tendency of the recrystallization fraction over electric current density is demonstrated to be well quantified by introducing the effective activation energy and temperature.
