A small angle X-ray scattering (SAXS) techniques has been used to characterize the interfaces between the {delta}{prime} phase and matrix in and 8090 Al-Li alloy aged at 160 C for several times. The results showed that a transition interfacial layer exists between the {delta}{prime} phase and matrix in the earlier stage of aging, which disappears in the later stage of aging. The existence of a transition interfacial layer indicated that the phase precipitates by spinodal decomposition. This mechanism is thought to be the cause of the deviation of {delta}{prime} phase coarsening from the LSW coarsening rate law.
