Atomic structure of T1 precipitates in Al–Li–Cu alloys revisited with HAADF-STEM imaging and small-angle X-ray scattering
Abstract
The structure of T1 precipitates which formed under ageing in Al–Li–Cu alloys has been studied using high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) imaging. Complementary information on the precipitate composition has been obtained on the same system by small-angle X-ray scattering (SAXS). According to HAADF-STEM imaging, the currently accepted structures based on the stacking of {111} type planes are ruled …
