摘要：

A theoretical model that describes split grain-boundary dislocations in low-angle tilt boundaries of high-temperature superconductors is suggested. It is shown that the dissociation of dislocations in low-angle tilt boundaries is usually accompanied by a decrease in their elastic energy and causes an increase in the critical current density across the boundaries in high-temperature superconductors.
