a Cross-sectional simulation after a virtual 365 days showing electrolyte potential field lines and current density vectors. Selective dissolution occurs primarily in the eutectic Al-Si phase, whereas the α-Al matrix exhibits negligible current density. b Final corrosion morphology after polarization, displaying characteristic intergranular and localized attack.
