Insights into precipitation characteristics and strengthening mechanisms in a low Cu/Mg ratio Al-Cu-Mg-Ag alloy

Using aberration-corrected scanning transmission electron microscopy, a new fully coherent precipitate platelet designated X′′, with a flexible atomic layer FCC structure, was identified in a low Cu/Mg ratio Al-Cu-Mg-Ag alloy. The emergence of the X′′ phase is primarily attributed to the preferentia...
