Abstract
Deformation of nanotwinned polycrystals subjected to uniaxial tensile loading is investigated by using massive parallel atomistic simulations. The following atomistic mechanisms associated with microstructure evolution are obtained: (i) formation and rotation of nanosized subgrains due to intensive dislocation – twin boundary interactions in nanotwinned grains; (ii) transformation of a specially orientated nanotwinned grain from a regular hexagonal shape to a rectangular shape; and (iii) thickening of a twin lamella controlled by grain boundary migration.
