ResumoAbstract The composition of {111} θ precipitate plates one and two unit cells thick in an Al-Cu-Mg-Ag alloy was investigated using an analytical transmission electron microscope with a field emission gun. These studies revealed that Ag and Mg segregate to the {111} habit plane interface and that some Mg may also be present within the precipitates. The effect of Ag and Mg on the nucleation behaviour of {111} θ precipitate plates is discussed.
