Diffraction Studies of the Atomic Structure of Large Angle [001] Twist Boundaries

The results of the application of diffraction techniques to study the atomic structure of grain boundaries are reviewed. The determination of the projected structure of a large angle [001] twist boundary is described. The influence of f.c.c. metal type and bonding type on boundary structure is examined. Generalizations are made concerning the structure of large angle [001] twist boundaries based on the results of the diffraction studies.
