The Effect of Load Frequency on the Temperature Dependence of Fracture Life of Notched Specimens for 9-12Cr Steel Under Creep-Fatigue Conditions
説明
<jats:p>In order to operate a thermal power plant safely, it is necessary to establish the prediction methods of fracture life for heat-resistant steels which is used in thermal power plant. For the establishment of prediction methods, it is necessary to consider the effects of creep damage and creep-fatigue interaction on the fracture life.</jats:p> <jats:p>Therefore, in this paper, creep-fatigue tests were conducted on notched specimens of W-added 9-12Cr steels for various temperatures and load frequencies. From these results, the influence of load frequency on temperature dependence of crack growth life for 9-12Cr steels was determined.</jats:p>
