外文摘要：Martensite is an important microstructure in ultrahigh-strength steels,and enhancing the strength of martensitic steels often involves the introduction of precipitated phases within the martensitic matrix.Despite considerable research efforts devoted to this area,a systematic summary of these advancements is lacking.This review focuses on the precipitates prevalent in ultrahigh-strength marten-sitic steel,primarily carbides(e.g.,MC,M2C,and M3C)and intermetallic compounds(e.g.,NiAl,Ni3X,and Fe2Mo).The precipita-tion-strengthening effect of these precipitates on ultrahigh-strength martensitic steel is discussed from the aspects of heat treatment pro-cesses,microstructure of precipitate-strengthened martensite matrix,and mechanical performance.Finally,a perspective on the develop-ment of precipitation-strengthened martensitic steel is presented to contribute to the advancement of ultrahigh-strength martensitic steel.This review highlights significant findings,ongoing challenges,and opportunities in the development of ultrahigh-strength martensitic steel.
