Small-angle neutron scattering from anisotropic single-crystalline materials
Isotropic small-angle scattering (SAS), ie without azimuthal dependence around the primary beam, occurs only for specific configurations of the scattering objects if single-crystalline material is studied. In the case of decomposing Ni-base alloy single crystals, SAS signals are generally highly anisotropic. From the analysis of 2-dimensional SAS patterns, it is possible to extract important information on the evolution of the morphology and on the 3-dimensional spatial arrangement of the precipitates from the early stages of decomposition. The real-space information obtained from transmission electron microscopy (TEM) is an excellent complement to the reciprocal-space information extracted from SAS data. The complementarity of these 2 techniques offers a valuable approach to study precipitation phenomena.
