A rebound mechanism for misfit dislocation creation in metallic nanolayers

A version of the Dregia–Hirth rebound mechanism for misfit dislocation creation is observed in atomistic models of Cu–Ni nanolayered structures. Glide dislocations in Cu layers undergo a reaction at the Cu–Ni interface under applied compression to produce another glide dislocation and a misfit dislo...
