Abstract
Dislocation model of a weak link at an intergrain boundary (IGB) with the misorientation angle theta is developed with the assumption of ord er parameter suppression in the regions subjected to strong stresses. Stress fields at the IGB with randomized dislocations (resulting from thermal fluctuations) provide a fast (exponential with respect to thet a) lowering of the critical current. The result agrees with the experi ments.
