MECHANICAL PROPERTIES OF IRRADIATED AND UNIRRADIATED FERRITIC/MARTENSITIC STEELS

摘要

Work in two areas will be reported. The first involves preliminary fracture toughness results obtained on unirradiated and irradiated F82H. Irradiations were in HFIR to about 3.8 dpa at 220-280 and 310-405℃. Embrittlement was observed for the low-temperature irradiation, with only small changes occurring at the higher temperature. In the second study, microstructure and mechanical properties studies were made on two Fe-12Cr ODS steels. One of the steels shows remarkable creep and tensile properties, and these results will be briefly discussed.
