Figure 2
Austenite orientation in a single ferritic grain. (a) An IPF-Z map. (b) A [111] pole figure in the ferrite crystallographic frame displaying the γ-orientation spread in a single ferritic grain. The orientations are colored using the IPF-Z color coding convention to relate to (a). The exact KS variants are plotted in green to emphasize the continuity of the observed OR. Only 1% of measured points of the data present on the spatial map are shown in the pole figure. (c) Histograms of rotational angle to the closest variant for four classical ORs in f.c.c. ↔ b.c.c. systems, showing that there is no single representative OR in the CF8M alloy. |
