Creep-fatigue interaction damage evolution and life assessment of 12Cr1MoVG steel high temperature header in power plants
Aiming at the problem of life loss of high-temperature headers of subcritical generator sets under the coupling of high-temperature creep and cyclic fatigue, this paper takes the high-temperature superheater outlet header of a power plant made of 12Cr1MoVG as the research object. Through finite element analysis, creep...
