Figure 2
Illustration of the nearest neighbor plane (Plane −1) of the parent lattice and its counterpart (Plane 1) for the twin lattice, which are parallel and in mirror symmetry with respect to the invariant plane K1 (Plane 0). The twinning shear vector t is represented by the displacement from a parent lattice point N to the nearest twin lattice position A′ on Plane 1. |
