(a) Atomistic model of a single twin (red atoms) embedded in the Mo matrix (blue atoms). Semitransparent blue spheres show the original positions of Mo atoms in the non-twinned matrix. (b) Stereographic projection {001} (matrix orientation) illustrating orientations of the twinning planes {112} and positions of the poles {110}, {200} and {221} from the upper hemisphere. (c) Atomistic model of the interface between two twin variants growing on differently oriented twinning planes, i.e. Mathematical equation and Mathematical equation [see panel (b)]. Green atoms belong to the minor variant having the orientation from equation (2c). The atomistic models were drawn using VESTA (Momma & Izumi, 2011View full citation). In the structure models, the solid boxes mark the elementary cell of Mo. The Burgers vectors Mathematical equation are depicted as cyan arrows. The dashed black box in panel (a) highlights the elementary cell of a superstructure oriented along the reciprocal space direction {211} (see text).
