Faceting the high-angle grain boundaries in SIGMA equals 3 and SIGMA equals 5 coincidence lattices of the f. c. c. structure was studied using thin-film bicrystal gold specimens of controlled geometry. A number of relatively high-index boundaries in the coincidence lattices was found to break up into low-energy facets corresponding to low-index planes of the coincidence lattices. These results are consistent with our general expectation that the grain boundary energy decreases as the planar density of coincidence sites increases.
