(a) Orientation map showing t|$\upalpha $| (red) and t|$\upbeta $| (blue) in a section of scan Py1. Crystal orientations are colored as in Fig. 5, |$\Sigma $|3 boundaries are marked in cyan and LABs are marked in black. Domains with moderately different orientations are frequently separated by diffuse transition zones. (b) Fifth neighbor kernel average misorientation maps using rainbow colors for the angular interval between 0.7|$^{\circ }$| (blue) and 1.8|$^{\circ }$| (red) of the same section as in a highlighting the diffuse transition zones and LABs (black solid lines). (c) Close-up of b showing the position of two orientation profiles in d. (d) Misorientation profiles showing point to origin (p-o) and point to point (p-p) misorientations for an LAB (purple) and a diffuse transition zone (green). The misorientation over the LAB is restricted to distances smaller than the step size of the scan of 100 nm. The cumulative p-o misorientation reaches 3|$^{\circ }$| over a distance of about 500 nm across the diffuse transition zone while the p-p misorientation remains below 1|$^{\circ }$|⁠.
