抄録

A technique to heal fatigue damage in a stainless steel by controlling high-density electric current was studied. The high-density electric current was applied to a fatigued specimen. A dislocation structure was observed by transmission electron microscope (TEM) before and after applying the high-density electric current. In addition, the effect of the temperature rise due to Joule heating on dislocation motion was investigated. The experimental results showed that the effect of electric current has a stronger influence on dislocation motion than the effect of temperature rise due to Joule heating.
