IPF maps, IPF density, grain boundary map, and kernel average misorientation map of the first specimen reconstructed from the 3D scan mode before and after thermal cycling. (a) The IPF (xs) map, (b) IPF (ys) map, and (c) IPF (ND) map of the first specimen with their high-magnifications before thermal cycling. Their IPF densities of the (d) xs axis, (e) ys axis, and (f) ND are described. The KAM map calculated with a 1° cut-off angle (g) and its statistical distribution before thermal cycling (h) are presented. The 3D IPF maps of the (i) xs axis, (j) ys axis, and (k) ND after thermal cycling show noticeable changes in orientation. Their IPF densities of the (l) xs axis, (m) ys axis, and (n) ND are shown. The KAM map after thermal cycling (o) and its statistical distribution (p) are also displayed. For individual grains shown in (a) and (i), grain A is broken into multiple small grains, while grain B becomes larger.
