Abstract
The occurence of disorientations in dislocation structures is investig ated for hot-compressed aluminium single crystals with [001] orientati on. The local orientations are determined by means of electron backsca ttered patterns (EBSP) for sampling points with a constant point dista nce smaller than the dislocation cell or subgrain size. Accordingly, a procedure for the evaluation of the measured orientations is develope d which takes into account that adjacent sampling points are separated by a dislocation boundary only occasionally. Additionally, the substr ucture of the crystals is characterized by rocking curves and TEM. (C) 1997 Elsevier Science S.A.
