An electron diffraction technique was developed to study the structure of high-angle grain boundaries. Diffraction patterns were obtained from the grain boundary region, and it was demonstrated for the first time that high-angle 〈001〉 twist boundaries have a periodic nature over the entire range of possible misorientations. Relatively strong grain boundary reflections corresponding to reflections from the O-lattice were obtained from all boundaries studied. These results indicate that atomic relaxations occur around the O-lattice points and these relaxations appear to be qualitatively similar to those which are well known to occur in low-angle twist boundaries
