Fig. 6: Semicoherent interface structure.
From: Coherent and semicoherent α/β interfaces in titanium: structure, thermodynamics, migration
a Reference dichromatic pattern formed by the BCC/β lattice (blue) and HCP/α lattice (red) for the BOR. The gray points denote the overlapped blue/red points. The gray-shaded region is a CSL unit cell; the narrow yellow-shaded region is a DSC unit cell. A Burgers circuit showing the closure failure is drawn; it corresponds to the closed circuit in (c). b Enlargement of the region framed by dashed lines in (a), showing the DSC lattice and the Burgers vector (denoted by a yellow arrow). c, d Show, respectively, the simulation result and TEM image of α/β interface structure viewed along the -e1-axis, while (e, f) show the views along the e2-axis. In (c, e), the red and blue atoms (colored according to the common neighbor analysis, CNA59) denote α and β phases respectively. d, f are TEM images reproduced with permission39 (Copyright 2018 Elsvier).
