The grain boundary ¡ -surface surface (the variation of the grain boundary energy during sliding) is calculated at ¢ = 5 [001] twist grain boundary in aluminum to study the effect of the sliding direction on sliding characteristics of twist grain boundary at atomic level. The sliding behavior is more isotropical than that in tilt grain boundary. The energy peak of the grain boundary ¡ -surface is smaller than that of the ¡ -surface without the grain boundary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
