Corrosion resistances of oxide dispersion strengthened ferritic steels containing 3.5wt% Al and 14–17wt% Cr were examined. Experiments were performed in stagnant lead–bismuth eutectic (LBE) containing 10 −6 and 10 −8 wt% oxygen at 550 and 650°C. The maximum exposure duration was 5000h. Observations of the cross-sections of exposed samples obtained by scanning electron microscopy and Auger electron spectroscopy suggested that a very thin Al oxide layer was formed continuously. The materials containing 3.5wt% Al exhibited good corrosion resistance despite being exposed to 5000h of LBE containing 10 −6 wt% at 650°C. Furthermore, a favourable influence of adding minor amount of Zr was detected after 5000h exposure to LBE containing 10 −8 wt% oxygen at 650°C.
