Figure 6
Comparison of grain structures revealed by DCT and EBSD on the same slice after registration [colour coding according to equation (6)]. (a) The EBSD orientation map, (b) the DCT cross-section obtained from registration, (c) the DCT map with superimposed EBSD grain boundaries (white: 1° < δ < 5°; red: 5° < δ < 15°; black: δ > 15°). The pixel size is 1.4 µm. The x and y unit vectors refer to the EBSD coordinate system, which has been flipped for consistency with Fig. 1. In part (a), the white asterisk marks the grain analysed in Fig. 7(b) and the black asterisk marks the grain which is missing in DCT. |
