Creep-fatigue tests of 9Cr-1Mo-V-Nb steel have been conducted under load control with further study of the steel mechanical degradation via microscopic observation, static-mechanical analysis and ultrasonic evaluation. The tempered specimens exhibited a tempered martensitic structure with a high dis...
