Microstructural evolution of pre-oxidized T91 steel during LBE dissolution corrosion

High Temperature Corrosion of Materials
Abstract The microstructural evolution of T91 steel by pre-steam oxidation during LBE dissolution corrosion was investigated. A bi-layered pre-oxide film with Fe-rich outer layer and Cr-rich inner layer was formed on T91 steel, which was similar to the oxide film of T91 after oxidation corrosion in LBE.
