SOME FURTHER MICROSTRUCTURAL CHARACTERISTICS OF FACE-CENTERED-CUBIC POLYCRYSTALLINE METAL THIN-FILMS

We have made detailed observations of gold thin films and commercial a luminum-copper alloy films, using transmission electron microscopy. Al l of the films embody a strong [111] fiber texture. We have measured t he misorientation distributions for the grain boundaries in these film s, and also determined the ''grain boundary character distribution'' i n terms of the coincident site lattice model. We show that in spite of their apparent similarity, these films embody significant differences in terms of these measures.
