Visualisation of the GBC distribution as measured by EDOR in polycrystalline Al. (a) GB misorientation distribution. The plot shows progressive slices of constant θ through the asymmetric fundamental zone for misorientations in cubic crystals. Each section comprises GBs within the specified range of θ±2.5° (indicated in degrees below each slice).43 (b) Distribution of the GB plane normal vectors plotted in the standard stereographic triangle for cubic symmetry.
