In studies of inorganic and biogenic structural materials, x-ray absorption microCT (micro Computed Tomography) can be combined to great effect with x-ray scattering. The techniques provide complimentary information, and the limitations of one are offset by the strengths of the other. For example, absorption microCT can supply an accurate, 3D map of the distribution of material within a solid specimen but cannot identify where different crystalline or amorphous phases are to be found (unless compositions or densities differ significantly) or what changes occur in the material itself (amount of plastic deformation, magnitudes of internal stress); this latter information is provided by x-ray scattering (diffraction from crystalline phases and small angle x-ray scattering, SAXS, from nm-sized structures) albeit at much lower spatial resolution. Three examples of studies combining the two approaches are presented: correlation of different scale of crystallographic texture with fatigue crack path and crack closure, studies of damage in monofilament composites and in situ loading of bone.
