Figure 3. TKD maps taken from a bottom layer. (A) TKD IPF map showing how hierarchical martensite structure impacts the thickness of deformation twins inside an α' lath. (B) The corresponding GB map on top of the image quality map. The colours used to mark different types of GBs are the same as in Figure 1. Black and white arrows point to linked and non-linked twins, respectively. (C) <1$$\overline{2}$$10> and (D) {10$$\overline{1}$$1} pole figures from the blue rectangle area in (A).
