Observation of intrinsic and extrinsic secondary grain boundary dislocations in (001) high angle twist boundaries in MgO
The report describes a systematic electron microscope investigation of possible GBD structures in (001) high angle twist boundaries in MgO using bicrystals of controlled geometry. Boundaries of this type were selected because they are relatively easy to prepare, and because GBD structures have been extensively observed and studied (3,4,7) in boundaries of this type in the metal gold.
