  "abstract": "The coupled effects of second-phase precipitates and deformation microstructures in AA2024 were investigated. Cold rolling is found to accelerate the precipitation of S-phase in initial T3 state through enhanced diffusion and heterogeneous nucleation on dislocations, leading to refined precipitate spatial distributions resulting in increased hardness, while promoting faster coarsening of the precipitates in the initial T8 condition (with S-phase volume fraction close to equilibrium). In parallel, the presence of non-shearable S-phase precipitates strongly influences deformation microstructures by increasing sub-boundary density and stored energy, and by modifying the spatial distribution of dislocations. Combined 2D and 3D analyses highlight more pronounced and more heterogeneous orientation gradients in the deformed grains of the initial T8 state with S-phase precipitates as compared to those of the initial T3 state without S-phase, emphasizing the role of precipitate dislocation interactions.",
