Abstract : Limitations which currently exist on using the electron microscope lattice imaging technique to obtain information about grain boundary structure are considered. Boundaries are only amenable when the adjoining crystals are oriented so that they produce projected patterns of resolved atomic columns or atomic planes. The conditions under which information can then be obtained about the atomistic core structure, the boundary translational state and the presence of localized grain boundary dislocations are described. In a number of instances, ultra-thin bicrystals are required which are so thin that great difficulties will be encountered with utilizing them on a practical basis.
