Effect of oxygen concentration and temperature on compatibility of ODS steel with liquid, Stagnant Pb$$_{45}$$Bi$$_{55}$$

Furukawa, Tomohiro  ; M$"u$ller, G.*; Schumacher, G.*; Weisenburger, A.*; Heinzel, A.*; Aoto, Kazumi 

In order to investigate the effect of oxygen concentration in LBE on corrosion behavior, exposure test of an oxide dispersion strength martensitic type steel was performed in stagnant lead-bismuth eutectic (LBE) containing 10$$^{-4}$$, 10$$^{-6}$$ and 10$$^{-8}$$wt% of oxygen at 500-650$$^{circ}$$C up to 10,000 hours. Results of metallurgical analysis, it was obtained that the base metal was protected from liquid metal corrosion by the formation of a spinel layer under the test condition containing 10$$^{-6}$$wt% of oxygen at 550$$^{circ}$$C or less. In LBE over 600$$^{circ}$$C containing 10$$^{-6}$$ and 10$$^{-4}$$wt% of oxygen, liquid metal corrosion was observed at some places on the surface. At the condition of 650$$^{circ}$$C containing 10$$^{-8}$$wt% of oxygen, although no oxide layer was observed on the surface, the base metal showed good compatibility with LBE.
