Disclination model of high angle grain boundaries
Abstract
Since the grain boundary is a rotational defect and so is a disclination, it is proposed here that a grain boundary may be made of disclinations instead of dislocations which are translational defects. The excess elastic energy for a symmetric tilt boundary whose orientation is between two low energy orientations is calculated by using this model. Such calculation cannot be easily performed using dislocations.
