Precipitation of the metastable and equilibrium phases has been studied by X-ray diffraction in ternary aluminum rich Al-Ag-Zn alloys. The precipitation sequence was found to be GP zones → ∈ → ∈ Lattice mismatch between the GP zones, ∈, and ∈ phases was found to depend upon the solute content of the alloy. The lattice mismatch between the metastable precipitates and the matrix could be altered by alloying or aging at 150°C.
