Figure 3
Reconstructions of the Al/SiC composite specimen. The area is 62 × 62 voxels (15 µm in-plane dimensions). Except as noted otherwise, the linear color table runs from lower to higher `intensity' using dark blue, light blue, yellow, red and dark brown; the relative `intensities' of the different reconstructions are given by the number in the lower-right corner of the panels [except (h)-(j)]; for reference, the `intensities' in panel (g) run from 250 to 0. Reconstruction with (a) Al 111; (b) Al 200; (c) Al 220. (d) Sum of the Al reconstructed slices shown in (a)-(c). Reconstruction with (e) SiC 10.1; (f) SiC 11.0; (g) SiC 10.2. (h) Sum of the three Al reconstructions (green) and of the SiC 11.0 reconstruction (blue) and SiC 10.2 reconstruction (red). (i) Reconstruction from transmitted-intensity data. (j) 2BM, APS, reconstruction of a slice near to the sampling plane in (a)-(i), recorded at 25 keV and reconstructed with 1.45 µm voxels. The reconstruction in (j) is scaled to match those in (a)-(i). In (i) and (j), black indicates the highest values of linear attenuation coefficient and white the lowest. (k) Reconstruction with diffracted intensity from the peak with d = 2.3 Å (the reconstruction with the d = 3.65 Å peak differs little and is not shown). (l) Reconstruction with d = 4.15 Å.  [article HTML]
