"Annealing twins in nanocrystalline fcc metals: A molecular dynamics simulation," PHYSICAL REVIEW B 75(18): 184111. DOI: 10.1103/PhysRevB.75.1841111098-0121http://hdl.handle.net/10919/25356We report fully three-dimensional atomistic molecular dynamics studies of grain growth kinetics in nanocrystalline Cu of 5 nm average grain size. We observe the formation of annealing twins as part of the grain growth process. The grain size and energy evolution was monitored as a function of time for various temperatures, yielding an activation energy for the process. The atomistic mechanism of annealing twin formation from the moving boundaries is described.application/pdfen-USIn CopyrightGrain-growthPlastic-deformationBoundaryCopperMechanismsEnergyDiffusionMigrationPhysicsArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevB.75.184111https://doi.org/10.1103/PhysRevB.75.184111
