(a) SEM micrograph of a nitrided whisker including several variants that exhibit faceting. The numbers denote the appropriate PTMC variants. (b) Superposition of the band contrast map with the IPF map of the nitrided iron whiskers corresponding to (a). The α–γ′ interface is marked with a blue line, if the deviation from the PTMC OR is ≤2°. The yellow line marks the Σ3 twin boundary between two γ′ variants, if the deviation is also ≤2°. Magnified area of the SEM micrographs of (c) Fig. 4[link](a) and (d) Fig. 4[link](c), showing a detailed view of the surface features for different variants. The numbers denote the appropriate PTMC variants and the green and blue arrows mark traces of {100}γ′ planes.
