摘要：

Computer simulations in frames of the 3D deformation-based model showed several unusual behavior of nanostructured Cu with high angle grain boundaries. This was the result of considerable activation of the processes of mutual dislocation annihilation and lattice dislocations absorption by grain boundaries.
