Fe-9 Cr-2 W基铁素体/马氏体（F/M）钢在铅冷堆中表现出高性能。然而，很少有研究动态应变时效（DSA）对Fe-9 Cr-2 W基F/M钢的影响。本文研究了Fe-8.5Cr-1.5W基F/M钢。通过对动态应变-应力曲线的分析，观察到了这种敏感性。当应变速率为10−3s− 1和10−4s−1时，在300 ~ 650°C范围内出现锯齿状流动。屈服强度和拉伸强度趋于平稳，但总体上从300 °C下降到500°C。初步的显微组织分析验证了Fe-8. 5Cr-1. 5 W基F/M钢的稳定性。这些结果为F/M制备工艺的优化提供了科学依据和指导。
Fe-9Cr-2W-based ferritic/martensitic (F/M) steels exhibit high performances in a lead-cooled reactor. However, there have been few studies that examined the dynamic strain aging (DSA) effect on Fe-9Cr-2W-based F/M steels. In this article, Fe-8.5Cr-1.5W-based F/M steel was examined. By analyzing the dynamic strain-stress curves, the sensitivity was observed. When strain rates were 10−3s−1and 10−4s−1, serrated flow occurred from 300 to 650°C. The yield and tensile strength plateaued but overall decreased from 300 to 500°C. The initial microstructural analysis verified the stability of Fe-8.5Cr-1.5W-based F/M steel. These results provide scientific basis and guidance for the optimization of the preparation process of F/M.
