Abstract
The interfacial structure and composition of θ′ (Al2Cu) precipitates in Al-0.9at.%Cu-0.9at.%Ag alloys were examined using high resolution electron microscopy. High angle annular dark field scanning transmission electron microscope (HAADF-STEM) images showed the presence of a silver(Ag)-rich bi-layer on the coherent (100) θ′-Al interfaces of the precipitates (1). Despite the presence of this layer, growth ledges were observed on the θ′ phase and thickening of the precipitates was able to proceed via ledges of step height 0.5c(θ′).
