The energy-misorientation relationship of grain boundaries in copper was measured by recording the rotation rate of a single crystaf sphere of copper sintered on to a flat single crystal of the same material. The results obtained suuggest that low-energy boundaries may exist at non-highcoincidence o
## Abstract The energy of coincidence boundaries is investigated for rotations about the [0001] axis in wurtzite GaN. A boundary may have two types of interfaces corresponding to the edge or diagonal of the unit cell of the coincidence site lattice. Their energy is shown to be a function of the str
If it acquires a screw orientation, it will dissociate into partials and glide on an octahedral plane; if it acquires an edge orientation, it will dissociate into a barrier and become sessile. This reasoning is in agreement with the failures to observe slip on cube planes in highly favorable stress
