Abstract
The relative energies of grain boundaries in silver chloride crystals have been measured. The measurements were made on tricrystals grown by simultaneously drawing three single crystals vertically from a melt. Tricrystals of three different isoaxial orientations, [Formula: see text], [Formula: see text], and [Formula: see text], were studied. The relative grain boundary energies were measured as a function of the orientation differences between two grains forming a boundary in crystals of each of the orientations given above. From these measurements the following conclusions are drawn: the grain boundary energies of silver chloride follow the equation of Read and Shockley; for small orientation differences, that is, differences less than 10°, the boundary energy is a function of the axial orientation of the grains forming the boundary; for large orientation differences, that is, differences greater than 10°, the boundary energy is not a function of the axial orientation, except when cusps occur; the maximum energy of a boundary made of crystals each with a [Formula: see text] axial orientation equals the maximum energy of a boundary between crystals of [Formula: see text] axial orientations.Keywords
