Measurements of the shape and dimensions of the pits and cracks formed in corrosion fatigue tests of a high-strength aluminium alloy, 7075-T651 were conducted by computed-tomography using ultra bright synchrotron radiation X-ray. Complex corrosion process could be observed and detail shape of corrosion pits could be identified. Sometimes, corrosion pit was formed under passive film, and those were not observed from the surface.
