In each notation, the indices refer to the grain boundary plane and rotation axis. From the geometrical laws regarding low-angle grain boundaries, it is expected that these five tilt grain boundaries consist of edge dislocations with b = 1/3 1120 , 1/3 1120 , 1100 ...
Websification is the distinction between tilt, twist and mixed-type (or general) boundaries (see e.g. Sutton & Balluffi, 1995). Most grain boundary studies and experimental data concern tilt and twist boundaries in cubic materials. Because of crystal symmetry, some pure twist boundaries can be also characterized as pure tilt boundaries. The best
