Implication

This research shows Ag microalloying improves mechanical properties and grain structure in Al–Cu–Mn–Mg alloys, suggesting new pathways for alloy design.

Key Points

Increasing Ag content leads to significant grain refinement, reducing average grain size from 15.3 to 11.3 μm.
The optimal 0.5 wt% Ag alloy shows remarkable mechanical properties, achieving an ultimate tensile strength of 503.4 MPa.
Precipitation strengthening, driven by the Ω phase, accounts for increased yield strength, rising sharply with Ag content.
This study employs a multiscale characterization approach, including tensile testing and various microscopy techniques.
