A study was made of the glide force due to stress on the constituent dislocations of slightly perturbed symmetric low-angle tilt boundaries. It was shown that the stabilizing force arose from both the long-range interaction of the constituent dislocations and their local line tension effect. A continuum model for this glide force was also presented. The results and continuum model provided a basis for further understanding of the stress-driven migration of distorted grain boundaries.
