摘要
The deformation of metallic materials up to large strains leads to the formation of fine grain structures (down to the nanometric scale) with high densities of grain boundaries and grain boundary junctions. Such structures demonstrate significant lattice rotations and the presence of disclination defects at grain boundary junctions. We present the results of transmission electron microscopy (TEM) observations of disclinations in strongly deformed metals and describe the theoretical approaches for their identification.
