Abstract

The formation of an edge dislocation from the surface of a cylindrical circular cavity lying in a high-angle grain boundary and separating two disclination dipoles located in the boundary has been investigated from a theoretical point of view. The energy variation due to the dislocation introduction into one grain has been determined, and the equilibrium positions (stable or unstable) of the emitted dislocation have been characterized as a function of the direction of the Burgers vector, the strength and length of the disclination dipoles.
