Elevated Temperature Creep-Fatigue-Oxydation Interactions in 9–12 % Cr Steels: Effects of Tensile/Compressive Hold Times on Fatigue Life

The 9–12%Cr martensitic steels are candidate materials for several components of the generation IV and fusion nuclear reactors. In these future applications, in addition to long holding periods, cyclic loadings corresponding to start and stopoperations and maintenance must also be taken into account. Creep-fatigue interactions must therefore be considered to design these components. A broad literature review showed that between 20°C and 650°C...
