Description

The atomic structure of a 0.94-nm-thick T1 precipitate in an Al–Cu–Li–Mg–Ag alloy is investigated by combining aberration-corrected scanning transmission electron microscopy (STEM) and energy-dispersive X-ray spectroscopy (EDX). Ag segregates at the first layer of the T1 precipitate interface, revealing a significant compositional variation of Ag throughout the interface. Moreover, the T1 precipitate thickened from 0.94 nm with successive stacking of identical 0.94 nm thick layers
