Abstract

Suppression of chromium depletion by grain boundary structural change during twin-induced grain boundary engineering of 304 stainless steel was discussed. Transmission electron microscopy results showed that the chromium depletion at a low-energy boundary segment introduced by twin-emission into a random boundary was smaller than that of the original random boundary after sensitization. It was found that low-energy segments in the grain boundary network disrupted the continuity of chromium depletion along the random boundary network.
