Dealloying-driven cerium deposition on IMPs in AAs. 3D schematic view of the mechanism of cerium precipitation mechanisms on individual Sphase (boxed in green; upper row), θ-phase (boxed in pink; middle row) and Al7Cu2Fe(Mn) constituent phase (boxed in yellow; lower row) embedded in the
alloy matrix. The mechanisms by which the cerium precipitates on IMPs along with the probable corrosion reactions occurring at IMPs are depicted in detail.
