Fig. 2.
3D maps obtained from the Rietveld analysis of the 3D-XRD-CT data collected at room temperature. Top: volume rendering of the normalised scale factors (phase distribution volumes). The values in the colorbar axes have been chosen to achieve the best possible contrast. Middle: volume rendering of the average crystallite size maps of CeO2, ZrO2 and NiO (colorbar axes in nm). Bottom: volume rendering of the lattice parameter a of CeO2 and ZrO2 unit cells (colorbar axes in Å)
