Irradiation Creep and Swelling from 400 C to 600 C of the Oxide Dispersion Strengthened Ferritic Alloy MA957
Recently, there has been a growing interest in the use of oxide dispersion strengthened (ODS) ferritic steels for fusion reactor applications. As part of an extensive study performed at PNNL on the ODS steel MA957 [1], irradiation creep tests were performed on pressurized tubes made from MA957 by two different methods. The tubes were made either by gun drilling alone or by a combination of rod drawing and gun drilling. The different fabrication methods were explored because ODS steels have been difficult to form. The pressurized tubes were irradiated in the Fast Flux Test Facility (FFTF) to doses ranging from 40 dpa to 110 dpa at temperatures ranging from 400 C to 600 C. The effective stresses resulting from the pressurization of the tubes ranged from 0 MPa to 175 MPa.
