Abstract: A small angle X-ray scattering (SAXS) technique was used to characterize the interfaces between the δ′ phase and matrix in 2091 Al-Li alloy aged at 150 ℃ for different times. The results show that a interfacial layer exists between the δ′ phase and matrix at aged earlier stage, which disappears at aged later stage.

Key words: Al-Li alloy, δ′ phase, small angle X-ray scattering
