Abstract In this paper, the isotherm method was used to extrapolate the results of the creep rupture strength test of the Super304H/T92 friction welding joint at 625 ℃. Service life prediction curves indicated that Super304H/T92 weld joints could ensure safe service for duration of 10⁵ h at 625 ℃, which is in according with the ultra-supercritical units steam conditions. The rupture process of the specimens is normal, and the fracture location is on the T92 heat affected zone. When the stress is higher, the rupture mode belongs to transcrystalline fracture, and results in forming dimples. When the stress is lower, the rupture mode belongs to creep rupture, and results in cleavage rupture. With the decrease of stress load and the extension of the fracture time, the number of dimples reduced significantly, the cleavage surface increased gradually, and plastic rupture transformed into cleavage rupture. This research provides the theoretical basis and experimental support for the further engineering application of the Super304H/T92 friction welding technology.
