Figure 3. MA distribution in freckle grains. (A and B) Band contrast map and orientation map. LAGBs are highlighted with white lines, and their MAs are marked. (C) MA distributions for the internal and external grains. (D) BSE image corresponding to the black square in image (B), and five freckle grains are outlined with a yellow dashed line. The freckle grain marked in red is chosen for the HR-EBSD analysis.
