Structure and Behaviour of Grain and Phase Boundaries.
Abstract
Thin film bicrystals have been created using gold, silver, palladium and platinum epitaxially grown single crystals. Low angle twist boundaries in all systems consisted of orthogonal sets of lattice dislocations, who character is in agreement with the O-lattice theory and earlier less general predictions. High angle boundaries in the Au-Pt system were seen to relax into dislocation networks at temperatures in excess of 600 deg. However, the dislocation directions and spacings could not be interpreted in terms of CSL and NCSL relaxations. All the experiments were rendered more difficult than anticipated because of the difficulties of making the continuous flat single crystals. A critique of the general method of thin film welding for the study of grain boundaries is included. (Author)
