Suppression of chromium depletion by grain boundary structural change during twin-induced grain boundary engineering of 304 stainless steel

An analytical transmission electron microscopic study of a twin-induced grain boundary engineered 304 austenitic stainless steel demonstrated 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.
