Creep-fatigue (Creep fatigue and fatigue) tests of Mod. 9Cr-1Mo steel have been performed by varying stress holding time at 550℃. Creep-fatigue properties are affected by stress holding, and strain rate increases with increasing stress holding time．In Vickers hardness measurements Vickers hardness of creep fatigue damaged specimen is larger than that of fatigue damaged specimen. In magnetic characterization the saturated magnetic flux density and permeability of creep fatigue damaged specimens are larg...
