Crystallization pressure and volume variation during rust development in marine and urban-continental environments: Critical factors influencing exfoliation

The rust layer formed on carbon steel exposed to natural marine and urban-continental envi-ronments for up to 50 years was studied. Mineralogical phase composition of the rust layer was evaluated by X-ray diffraction (XRD), akaganeite, goethite, lepidocrocite, magnetite, and amorphous phases were id...
