Abstract : α′ precipitation in a Fe-19 at.%Cr alloy aged at 500 °C up to 2008 h has been characterized by both APT and SANS. This paper shows that when using an appropriate method for SANS data treatment, both APT and SANS yield consistent results regarding not only volume fraction and size but also α and α′ composition. Good agreement is achieved when α′ particles are considered as magnetic scattering features at the early stage of the kinetics.
