Abstract
The boundary dividing a plane with rational indices, for example, (100) and (110) in a cubic lattice, is considered. The planes are oriented so that the direction [001] is common. Then the interatomic distances are incommensurable in the perpendicular direction. The conditions of thermal activation slip along such a boundary are studied. For sufficiently small stresses the dependence of the derivative of the slip velocity on the stress has a discontinuous nature.
