Figure 7. SEM image, ND-IPF and GB maps of another portion of a 600 μm long longitudinal cross section, a portion of which was also shown in Figure 3c and d, showing that comparatively rare, but highly misaligned regions do exist in the Bi2212 filament.

As shown in (b), most grains are well textured and in this case green, which denotes that [010] is parallel to the ND. There is also a highly misoriented red-orange region indicating that c-axis [001] oriented grains are present. (c) Although the majority of GBs are colored green (<20°), the colony boundaries have much larger misorientation, signifying that they contain a large component of out-of-plane misorientation.
