Cyclic deformation and damage mechanisms of 9%Cr steel under hybrid stress-strain controlled creep fatigue interaction loadings

•The hybrid-controlled creep-fatigue interaction (HCFI) tests have been performed.•All of the conducted HCFI tests can be divided into two regions.•The failure mechanisms of the HCFI tests in different regions have been clarified.•A new life prediction method based on the steady growth rate has been...
