Abstract

A high angle grain boundary in titanium containing a regular dislocation network has been studied using transmission electron microscopy. It was shown that the reference structure for this grain boundary was unlikely to be a CCSL and that a more feasible reference structure corresponded to the existence of near-2d periodicity in a plane which made a small angle with the grain boundary plane. The dislocation arrangement that would be required to accommodate the angular deviation from the relative orientation for this reference structure was calculated using an 'O' lattice method. This showed a good semi-quantitative agreement with that which was observed experimentally indicating that the proposed reference structure was the one adopted by this grain boundary.
