Abstract

The structure of low-angle tilt boundaries in magnesium-aluminate spinel has been studied by transmission electron microscopy. Special low-angle boundaries have been prepared from bicrystals but also boundaries in polycrystalline spinels were studied. The dislocations were all dissociated into partials. Their dissociation widths were found to increase with deviation from stoichiometry. Observations at lattice dislocations indicate that the composition at the boundaries may be different from the nominal composition.
