Figure 9
GND density maps (hexagonal grid EBSD data) of the austenitic phase of an austenitic/martensitic steel, calculated from (a) raw orientations [\underline{\underline{{\bf g}}}] and (b) orientations filtered by the LLASS filter [\underline{\underline{{\bf g}}}_{{\rm filt}}]. Blue arrows point to areas where the GND density is considered to be – at least partially – an artefact due to the orientation noise; magenta arrows point to areas where the GND density is more likely to be representative of actual dislocation structures.
