WebThe specimens were irradiated at 550/sup 0/C to damage levels of 8 to 12 dpa and transmutation helium levels of 300 to 500 at. ppM. Fatigue testing at 650/sup 0/C revealed that cyclic life was not significantly affected by the irradiation. However, unlike the results of tests of the same material at 550/sup 0/C, no endurance limit was observed.
