N2 - A [100], 45° twist plus 17.5° tilt mixed character aperiodic grain boundary in aluminium has been studied by high-resolution electron microscopy. Most of the boundary is asymmetric and exhibits coherency and/or anticoherency dislocations due to lattice mismatch across the interface. The boundary structure was found to be constituted of two basic structural units and could not be characterized on the basis of coincident-site lattice, displacement shift complete and the O-lattice geometric models of grain boundaries. Steps and microfacets observed at the boundary have also been characterized within the framework of the same structural unit model.
