Figure 7
(a) A 3D representation of the mutual orientation of the cubic β phase (black) and one of the 12 α crystallographic variants (red). The blue plane is the habit plane of the α variant (the blue triangle indicates the intersection of this plane with the β cube). The red-coloured planes denote (110)β||(0001)α. (b) A perpendicular view of the (110)β||(0001)α plane showing the indexing. The a1 axis of the hexagonal lattice was assumed to be the one aligned perfectly with the direction according to the Burgers OR. The c axis [0001]α and the [110]β direction point forward from the sketch. |
