Abstract

In the present communication some approaches for the interpretation of non-isotropic small-angle scattering (SAS) patterns commonly encounters in coherent precipitation processes of metallic alloys will be presented. In Ni-base alloys the SAS is generally highly anisotropic. It is shown that the combination of transmission electron microscopy (TEM) with the model fitting of SAS data is an efficient way to characterize the microstructure of metallic systems. The imaging capabilities of TEM can deliver critical information for the SANS models concerning the shape and arrangement of the precipitates. TEM particle size distributions can be used to monitor the ones obtained from the scattering data analysis.
