On the Precipitation in an Ag-Containing Mg-Gd-Zr Alloy

The evolution of precipitates in a high-strength Mg-2.4Gd-0.4Ag-0.1Zr (at.xa0pct) alloy was investigated using high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). The precipitation of Mg-2.4Gd-0.4Ag-0.1Zr includes β- and γ-type precipitates, the latter involving a hitherto unreported precipitation sequence that is the focus of the present study. The β-type precipitation sequence is described as follows: supersaturated solid solution (S.S.S.S.)xa0→xa0ordered solute clustersxa0→xa0zigzag GP zonesxa0→xa0β′xa0→xa0
