等温时效模拟研究12Cr1MoV钢在长期高温服役过程中碳化物的转变规律
Carbide Transformation Rule of 12Cr1MoV Steel Serviced for Long-Term at High Temperature Studied by Isothermal Aging Simulation
摘 要
通过等温(630 ℃)时效模拟试验,用碳化物电解萃取、X射线衍射定量分析等方法研究了不同服役时间12Cr1MoV钢中碳化物的转变情况,总结了它的转变规律.结果表明:12Cr1MoV钢在长期高温服役过程中的碳化物种类保持不变,均为M3C、M7C3、M23C6和MC;在0~8×104 h服役期间,碳化物总含量增加较快,超过8万h后碳化物总含量趋于稳定;在8万h以内,随着服役时间的延长,M3C含量逐渐减少,M23C6、M7C3含量逐渐增加,MC几乎保持不变;8万h以后,M3C、M7C3和MC趋于稳定,M23C6仍有少量增加.

Abstract
Carbide transformation in 12Cr1MoV steel serviced for different times was studied by using X-ray diffraction quantitative analysis after electrolytic extraction in isothermal (630 ℃) aging simulation test.And the transformation rule was concluded.The results show that carbide types in 12Cr1MoV steel unchanged during service processing at elevated temperature,including M3C,M7C3,M23C6 and MC.Total carbide content increased quickly as the steel serviced for 0~80 000 h ,and then grew stable after 80 000 h.M3C content decreased while M23C6 and M7C3 contents increased with the serviced time increasing before 80 000 h ,M3C,M7C3 and MC grew stable while only M23C6 increased a little after 80 000 h.
