Al-containing ODS steels with improved corrosion resistance to liquid lead-bismuth

► Corrosion resistance of these Al-containing ODS steels in lead-bismuth eutectic containing 10-6 wt% oxygen was investigated. ► The test temperature was 650 and 700 °C and the maximum exposure duration was 10000 h. ► Al surface alloying by pulsed electron beam improved corrosion resistance. ► Al addition to the matrix with small amounts of Zr or Hf was also effective.
