  text: Tribological shearing of polycrystalline metals typically leads to grain refinement
    at the sliding interface. This study, however, shows that nanocrystalline metals
    exhibit qualitatively different behavior. Using large-scale atomistic simulations,
    we demonstrate that during sliding, contact interface nanocrystalline grains self-organize
    through extensive grain coarsening and lattice rotation until the optimal plastic
    slip orientation is established. Subsequently, plastic deformation is frequently
    confined to localized nanoshear bands aligned with the shearing direction and
    emanating from voids and other defects in the vicinity of the sliding interface.
