Figure 4: Atomic view of the basal/prismatic transformation.
From: Twinning-like lattice reorientation without a crystallographic twinning plane
(a) The parent HCP frame (blue) and ‘twin’ HCP frame (red) as well as their possible transformation route via shuffling atomic rearrangements. The right-bottom atoms (half blue and half red) were chosen to be the reference point. (b–e) MD simulations showing the migration of basal/prismatic (BP) and prismatic/basal (PB) interfaces under compressive loading. The coherent TB (CTB) is present despite of the 90° (rather than 86°) lattice orientational relationship, because there are coexisting dislocations at the boundary. See Supplementary Information for simulation details.
