Abstract
Utilizing bicrystallography in two dimensions (2D), the symmetries of migration related segments of Coincidence Site Lattice (CSL) boundaries are predicted for projections along their [001] tilt axis in grain boundaries of crystalline materials that possess the holohedral point symmetry of the cubic system. These kinds of “edge-on” projections are typical for atomic resolution imaging of such tilt boundaries with Transmission Electron Microscopes (TEM). Such images from a recently published aberration-corrected Z-contrast scanning TEM investigation [H. Yang et al., Phil. Mag. 93 (2013) 1219] and other studies facilitate the direct visual confirmation of our frieze symmetry predictions with experimental results.
