The corrosion behavior of dispersion-strengthened ferritic Fe-13Cr-2Mo (TiO2) steel in oxygen-containing lead melt is investigated at 550 and 650°C. It is determined that duplex magnetite scale is formed on the steel surface at 550°C and oxygen concentration of about 10−3 wt.% in the lead melt. The scale grows symmetrically with regard to the initial steel-melt interface toward the liquid metal and...
