Quench sensitivity in Al–7Si–Mg alloys arises from interactions among solute, precipitates, dislocations, and the thermally mismatched Si phase, yet the direct role of Si in deformation after different cooling rates remains insufficiently understood. In this study, we combine experiments with crystal plasticity finite element modeling (CPFEM) to clarify how Si governs the mechanical response of an Al-7Si-0.4Mg alloy subjected to water quenching (WQ) and air cooling (AC). Rapid quenching produces high dislocation densities—particularly near Al/Si interfaces—due to severe thermal-mismatch deformation, while slow cooling results in a much lower initial dislocation content. These differences strongly influence subsequent aging, leading to significantly higher precipitate density and slip resistance in WQ-A than in AC-A specimens. CPFEM reveals that the matrix away from the interface dominates the macroscopic quench sensitivity, contributing most of the strength drop from WQ to AC. However, local deformation is controlled by the Si phase: AC-A specimens have lower dislocation density and precipitates at the Al/Si interface, which results in lower plastic deformation resistance, the intense strain localization at interface-adjacent matrix promotes early cracking, whereas WQ-A specimens show more homogeneous strain distribution and fracture through Si particles due to higher strength of the matrix near the interface and stress accumulation within Si. The integrated experimental–simulation framework elucidates how Si modulates dislocation evolution, strain partitioning, and crack initiation under different cooling rates, providing mechanistic insight for reducing quench sensitivity in Al–Si–Mg alloys and other multiphase systems with thermal-expansion mismatch.
