Figure 7
(a) IPF maps of the two surfaces of a nitrided whisker. The green rectangles mark the areas used for the (b) {100}γ′ pole figures. The blue circles in the {100}γ′ pole figures indicate the {100}γ′ poles of the appropriate PTMC variants. The α–γ′ interface in the IPF maps is marked with a blue line, if the deviation from the PTMC OR is ≤2°. (c) SEM micrographs of the two surfaces. The green lines mark the related surfaces in the SEM micrographs. (d) Habit plane locus for the PTMC prediction and the experimentally measured habit plane (black: α-Fe; red: γ′-Fe4N). The γ′ orientation corresponds to the identified PTMC variant with respect to α. The habit plane trace corresponding to the PTMC variant is marked with a blue line in the SEM micrographs. |
