Abstract
A transmission electron microscopy study and geometric analysis has been performed on a vicinal 78.7° high-angle grain boundary in pure Ti which has mixed tilt-twist character and exhibits a characteristic dislocation arrangement. There is no feasible constrained coincident site lattice which could be adopted as the reference structure by this boundary and an alternative structure is proposed which corresponds to a two-dimensional atomic arrangement inclined at about 18° to the boundary plane. The dislocation configuration required to accommodate the deviation from the reference structure orientation was predicted using an O-lattice algorithm for class 1 interfacial dislocations and this matched well the arrangement observed experimentally.
