An Al-1.08 vol.％ Si alloy was cold rolled to a reduction of 98％ (εvM =4.5) and then annealed at different temperatures up to 250 ℃ for different times.The morphologies of the Si particles were characterized and their effects on the microstructure and mechanical properties of the deformed and annealed samples were investigated.The deformed structure is characterized by a nanoscale lamellar structure with the presence of Si particles of coarse (＞ 1 μm), medium (100 nm-1 μm) and fine (＜ 100 nm) sizes in the matrix.The fine Si particles are aligned along the lamellar boundaries indicating a stabilizing effect on the structural refinement during cold rolling.
