Abstract
A very general model of symmetric and asymmetric tilt boundaries has been formulated and applied specifically to the simple cubic structure. In particular, it is shown that the grain boundary may comprise crystal lattice glide dislocations associated with both primary and secondary slip planes in the two adjacent grains. Two unique types of grain boundary are easily recognized by this formulation. The first is the stable grain boundary from which the concept of coincidence boundary orientation is readily obtained. The second is the unstable grain boundary characterized by long-range stress fields.Keywords
