Abstract

The atomic structure of secondary dislocations at Σ = 3, [1̄10]-(1̄1̄1) grain boundaries in pure aluminium have been studied by high-resolution electron microscopy. In defect-free regions, the grain boundary coincident-site lattice is continuous across the interface but several different secondary grain-boundary dislocations are observed in the vicinity of interplanar steps.
