Abstract
Cooperative grain boundary sliding (CGBS) (sliding of grain groups alo ng surfaces formed by sliding grain boundaries), has been considered a s a result of rigid shear of grain rows or as sequential shear of grai ns. The sequential shear of grains has been analysed in terms of movem ent of cellular dislocations (imperfections in regular grain structure ). Localized and extended cellular dislocations are examined. Coupling of CGBS and cooperative grain boundary migration might take place as the result of movement of grain boundary dislocations associated with ledges.
