Summary

Large scale atomistic simulations of model nanocrystalline materials are used to investigate the plastic deformation mechanisms active in interface dominated materials, with the view to understanding the origin of the related high strength seen in experiment. Results are presented detailing both inter- and intra-granular deformation processes under uniaxial tensile and nanoindentation loading conditions.
