Compatibility of structural materials with liquid lead-bismuth and mercury
Both liquid Hg and Pb-Bi eutectic have been proposed as possible target materials for spallation neutron sources. During the 1950s and 1960s, a substantial program existed at BNL as part of the Liquid Metal Fuel Reactor program on compatibility of Bi, Pb, and their alloys with structural materials. Subsequently, compatibility studies of Hg with structural materials were performed in support of development of Rankine-cycle Hg turbines for nuclear applications. This paper reviews our understanding of the corrosion/mass-transfer reactions of structural materials with these liquid-metal coolants. Topics discussed include the basic solubility relations of Fe, Cr, Ni, and refractory metals in these liquid metals, results of inhibition studies, role of oxygen on corrosion, and specialized topics such as cavitation corrosion and liquid-metal embrittlement. Emphasis is on utilizing the understanding gained in this earlier work on the development of heavy-liquid-metal targets in spallation neutron sources.
