Implication

Combining experiments and simulations shows how copper modulates mechanical properties in Al-Si-Mg alloys, indicating potential for improving performance.

Key Points

This work aims to investigate the effects of copper on the precipitation behavior and mechanical properties of Al-Si-Mg alloys.
Conducted multi-scale simulations and experimental testing
Analyzed the effects of varying copper content (0-4 wt.%)
Measured yield strength and ductility changes
Studied dislocation interactions through atomistic simulations
Yield strength increased from 285 MPa to 364 MPa with higher copper content
Ductility decreased from 10.1% to 6.8% as copper increased
Identified the dominant precipitate evolution as β′′ → β′′ + QP → QP → QP + θ′
Mechanistic change in dislocation interaction linked to strength-ductility trade-off
