The structure of (1(formula presented)01) twins in Ti films evaporated on NaCl substrates held at 250°;C has been examined by high-resolution electron microscopy. The analysis, using computer simulation, showed that it is necessary to derive a new model for the twin boundary in order to match the experimental images. The atomic structure of the twin interface contains both mirror and glide operations across a slightly-puckered (1(formula presented)01) plane. The newly derived models, which are called the displaced double plane (DDP) mirror and glide models give an excellent fit to the experimental images. The DDP glide model is structurally more reasonable, in terms of bond lengths and angles, as well as coordination of polyhedral linkages, than alternative proposals discussed in the recent literature.
