Precipitate characterisation in metallic systems by small-angle X-ray or neutron scattering.

Résumé

Small-angle scattering enables the extraction of precise, quantitative information about nano-scale precipitate microstructures. It can be used with X-rays (SAXS) or neutrons (SANS). This paper presents simple methods for extracting information on the precipitate size and volume fraction from SAS spectra. The various possibilities for obtaining precipitate size are reviewed, and the meaning of their differences is discussed. Examples of applications for complex precipitate microstructure measurements are given in the following areas: kinetic in-situ measurements in Fe-Cu and Fe-Nb-C alloys, non-stoichiometric precipitation in an Al-Zn-Mg-Cu alloy studied by anomalous SAXS (ASAXS), and precipitation mapping in weld cross-sections.
