| 英文摘要 | Addition of small amount of boron (B) in the (9 similar to 12)%Cr martensitic heat resistant steels can obviously prohibit the Ostwald ripening of M23C6 carbides so as to improve creep strength as well as creep rupture life. With the purpose of taking full advantages of B element, it is critical to make B preferentially distribute in (9 similar to 12)%Cr martensitic heat resistant steels. The mechanism of B preventing M23C6 carbides from ripening is also on the premise of dearly identifying the preferential distribution of B in the steels. Much concern has been growing over the preferential distribution of B in the research of (9 similar to 12)%Cr martensitic heat resistant steels. Therefore, this article gives a review on this aspect. Following a summary of the effect of B on mechanical properties, several commonly used characterizing methods for B segregation in the steels are introduced. Based on the physical metallurgy and the solution, diffusion mechanisms of B element, discussions on the preferential distribution of B element at prior austenite grain boundaries and in the M23C6 carbides as well as the related factors are emphasized. At last, two prevalent mechanisms of B restraining the coarsening of M23C6 carbides in (9 similar to 12)%Cr martensitic heat resistant steels are given by an intensive explanation so that the relationship between the preferential distribution of B and its advantage of increasing creep performance by suppressing the ripening M23C6 carbides are systematically elaborated, which gives a deep understanding of the role of B element in (9 similar to 12)%Cr martensitic heat resistant steels. |
