摘要：

It has been shown that the disclination dipole description of a grain boundary is equivalent to the surface dislocation model in the limit of low angular misorientations. Neither model is compatible with the classical formulation of Burgers, which is shown to be incomplete. For larger angles, on the other hand, the situation becomes more complex, and the surface dislocation approach is seen to be the most desirable. © 1990 Taylor & Francis Group, LLC.
