Embrittlement of Ferritic ODS Steel in Pb and Pb-Bi Coolants
Original language description
Oxide dispersion strengthened (ODS) steels are strong candidates for use as structural materials in future energy production systems, including generation IV fission reactors, fusion reactors and spallation neutron sources. The aim of this work was to describe microstructural changes in ODS steel (ODM401) caused by long-term high-temperature exposure to liquid Pb and Pb-Bi metals environments. Tensile and impact bend tests were used to observe oxide scale development and microstructural changes. The surface oxide layer of the steel was depleted in Cr and Ti when exposed to liquid Pb and Pb-Bi. The embrittlement of ODS steel following exposure to liquid Pb and Pb-Bi was greater than embrittlement caused by isothermal aging. The degradation of mechanicalproperties of the steel in liquid metals was caused by porosity development, precipitates coarsening and corrosion damage during long-term high-temperature exposure in liquid corrosive media.
