| 摘 要： | 运用Thermo-Calc软件进行热力学计算,预测了一种新型9-12%Cr低活性F/M(铁素体/马氏体)实验钢的组织。对淬火回火热处理后的显微组织进行了观察,并对析出物进行电子衍射结构分析和EDS化学成分检测。结果表明,实验钢是典型的回火板条马氏体组织,位于各种晶界上的析出物均为富Cr的碳化物M_(23)C_6,其化学成分随碳化物的形貌变化而变化。对实验钢进行60%冷变形并随后在820℃退火10-300 min,M_(23)C_6在完全再结晶、奥氏体相变过程中进一步球化,Cr、W不断富集,Cr/Fe逐渐升高至2后成分趋于稳定,化学组成接近于(Cr_(15)Fe_6W_2)C_6。

| Abstract: | Thermo-Calc software was used to predict the microstructure of a new 9-12%Cr lowactivation F/M steel designed for SCWR fuel cladding tube material.The microstructure of the experimental steel after quenching-and-tempering heat treatment was observed,and the chemistry and other characteristics of the precipitates were studied.The results showed that the experimental steel had a typical tempered martensitic structure.The precipitates located in various boundaries were Cr-rich carbides M_(23)C_6.After quenchin... |
