WebA thin GB structure study has been carried out for low-angle symmetrical tilt GB 90 [100] in Al. Such GB may be formation at misorientation on angle 90 by a turn around axis [100]. For this misorientation angle the boundary has a non-periodical structure. Atomic interaction was approximated by Morse's empirical potential. Webtan𝜓=tan(𝜑⁄2)⁄sin(𝜃⁄2) was found experimentally for low angle [111] symmetrical tilt grain boundaries [20, 21]. However, for grain boundaries with in-plane angles between ~ 15° to 30° shown schematically in Fig. 1a-b, the predicted out-of-plane rotation (Fig. 1c) was observed only locally close to the triple WebFeb 24, 2012 · Figure 1.
