Title:

P91 Steel: Creep-Fatigue Crack Growth Measurements

Abstract:

This data set contains experimentally measured creep-fatigue data obtained from P91 9Cr-1Mo steel according to ASTM standard E2760-10, Standard Method for Creep-fatigue Crack Growth Testing. All testing was performed on 50-mm wide C(T) specimens at a temperature of 625°C using trapezoidal waveforms. The specimens were prepared from material samples cut from a retired pipe owned by the Electric Power Research Institute. The tests were conducted in nine laboratories around the world as part of an EPRI-sponsored effort to validate the ASTM standard and assess precision and bias in the data generated using the specified procedures. The dataset includes test parameters, specimen details, raw measurement data, calculated values, and analyses as well as reference data and contact information. A limited number of creep crack growth rate tests were also conducted, and the results are included as well. The EPRI-led effort to evaluate the ASTM creep-fatigue crack growth test standard is described in a report that was published upon completion of the project.
