Abstract

The interfacial structure and composition of theta (Al 2Cu) 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) ? -Al interfaces of the precipitates (1). Despite the presence of this layer, growth ledges were observed on the ? phase and thickening of the precipitates was able to proceed via ledges of step height 0.5c(? ).
