Slip continuity across grain boundaries in aluminum Davis, Keith Gordon

Abstract

A study of slip continuity across grain boundaries in high-purity aluminum has been carried out, both on bicrystals and on polycrystal strip. Metaliographic methods have been used to show that slip continuity is not confined to the surface, but is a true continuity present within the metal. Orientations favouring continuity have been determined, which indicate that screw dislocations can pass through grain boundaries more easily than edge or mixed dislocations.
