A special mechanism of dislocation nucleation in deformed nanocrystalline metals and ceramics is theoretically described. The mechanism represents non-local homogeneous nucleation of a nanoscale loop of ''non-crystallographic" partial dislocation whose Burgers vector magnitude continuously grows dur
