Lead (Pb) and lead-bismuth eutectic (LBE) have found an important application as the nuclear coolants in Generation IV Fast reactors, and fluids for energy storage and heat transport in concentrating solar power systems, due to their desirable thermal properties and low reactivity. In order to improve thermal efficiency, operating temperatures should elevated up to 800 oC. However, the environmental degradation of many structural materials in Pb and LBE above 500 oC is a main issue, so the appropriate structural materials must be found or designed. In this work, the results of the exposure of niobium (Nb), Ti-V alloy, and Fe-Cr-Al steels to liquid Pb and LBE in static corrosion tests at 700 oC under oxygen-controlled conditions are presented. Post-corrosion characterization by microstructural analysis methods compares the corrosion resistance (anti-degradation properties) of tested materials in Pb and LBE, and leads to an assessment of the optimum liquid-solid combination.
