摘　　要：研究了在役高压锅炉(540℃、9.8 MPa)运行时间对12Cr1MoVG低合金钢(主蒸汽管道)组织性能的影响,观察了母材和焊接接头的宏观形貌及微观组织,测试了不同参数下母材和焊接接头的硬度,讨论了运行时间对母材和焊接接头力学性能的影响。The effect of operating time on the microstructure and properties of 12Cr1MoVG low alloy steel(main steam pipeline)in service high-pressure boilers(540℃,9.8 MPa)was studied.The macroscopic morphology and microstructure of the base material and welded joints were observed,and the hardness of the base material and welded joints under different parameters was tested.The influence of operating time on the mechanical properties of the base material and welded joints was discussed.

关 键 词：高压锅炉 主蒸汽管道 运行时间 硬度
