Abstract Nanostructured metals contain vast amount of grain boundaries which are crucial to their mechanical
behaviors. The plastic deformation mechanisms mediated by grain boundaries have been attracted
increasing attentions in recent years. Our recent studies have been focused on using atomistic simulations
to understand the grain boundary mediated plastic deformation mechanisms including deformation
twinning initiated by dislocation nucleation from grain boundaries [1], cyclic plastic deformability governed
by reversible slip of grain boundary dislocations [2], and extreme shear deformation of nanocrystals induced
by twin boundary sliding [3]. We have also proposed a misorientation-dependent model to explain the More >
