Abstract
The structure of {l_brace}11-bar 01{r_brace} twin dislocations in Ti films evaporated on NaCl substrates at 250 deg C has been examined and characterised by high-resolution electron microscopy. The results have revealed that a twin dislocation structure with step height 4 x d(K{sub 1}), where d(K{sub 1}) is the spacing of the {l_brace}11-bar 01{r_brace} twin planes, actually dissociates into two {l_brace}11-bar 01{r_brace} twin dislocations with step heights of d(K{sub 1}) and 3 x d(K{sub 1}). The twin dislocation with a step height of 3 x d(K{sub 1}) contains an edge dislocation in the core while that with a step height of d(K{sub 1}) is a simple classical twin dislocation structure. Twin dislocations with step height of 2 x d(K{sub 1}), including an edge dislocation in the core, also occur. The atomic-scale core structures of {l_brace}11-bar 01{r_brace} twin dislocations may be derived by analysis of the high-resolution images. The relative mobilities of the three types of twin dislocations is then discussed. 17 refs., 4 figs.
