Abstract Based on the development and needs of fourth-generation nuclear reactors, lead-based reactors with low melting point have become one of the current research hotspots. As a coolant in lead-based fast reactors, the effect of lead-bismuth eutectic alloy (LBE) on the fracture properties of ferritic/martensitic steels has become a research hotspot. This paper summarizes the research progress of compatibility of ferritic/martensitic steels in liquid lead and bismuth, including liquid metal corrosion (LMC) and liquid metal embrittlement (LME) and analyzes the fracture mechanics in liquid metal environment. The test method is used to describe the effect of liquid lead-bismuth eutectic alloy on the fracture properties of ferritic/martensitic steel. Finally, the microscopic mechanism of the fracture of ferritic/martensitic steel in liquid lead-bismuth is summarized.
