摘要：
Al-Li alloy has been widely used in the aerospace field due to its low density, high specific strength, high specific stiffness and excellent corrosion resistance. However, Al-Li alloy has certain quenching sensitivity, which limits its application in large-scale structural parts. In this paper, the research status of quenching sensitivity of Al-Li alloy in China and abroad was summarized. Firstly, the research methods of quenching sensitivity were introduced. The factors affecting quenching sensitivity were analyzed around alloying elements, plastic deformation and heat treatment process. Finally, the effects of microstructure evolution and precipitation behavior during quenching on aging microstructure and properties were expounded. The difficulties and key problems worthy of further exploration in future research were put forward. © 2024 Central South University of Technology. All rights reserved.
