Liquid lead–bismuth eutectic (LBE) can serve as a heat transfer fluid for advanced nuclear applications as well as concentrated solar power but poses corrosion challenges for the structural materials at elevated temperatures. Oxide passivation of the surfaces of these materials during exposure to liquid LBE can inhibit such material degradation. In this study, transmission electron microscopy of oxides formed on Fe-Cr-Al alloy during exposure to lowoxygenated LBE at 800C has been performed. A complex structure of the oxide film has been revealed, consisting of a homogeneous inner layer of mostly Al₂O₃ and a heterogeneous outer layer.
