Figure 14
An example of incomplete annealing twin indexing in reconstructed lath martensite (see Section 4.1[link]). (a) An α′ inverse pole figure map, showing grain boundaries in black and clusters formed with Code 8[link] in red. (b) A reconstructed γ grain containing annealing twin boundaries in pink. (c) The individually best fitting γ orientation for each orientation pixel. The scale bars are 10 µm. (d) (001)γ pole figures of the γ (blue square markers) and twinned γ orientations (grey square markers) from (b). The α′ variants according to the K-S OR are shown by round markers. Variants of packet 1 of γ and packet 4 of twinned γ are shared and shown using green round markers. (e) The variants of the experimentally refined orientation relationship, showing a 2.8° misorientation between the shared variants.
