Effect of helium preinjection and prior thermomechanical treatment on the microstructure of Type 316 SS
Samples of 316 SS were preinjected with 15 appM helium either hot (650/sup 0/C) or cold (room temperature) and irradiated with 3 MeV Ni/sup +/ ions to a dose level of 25 dpa at 625/sup 0/C in order to test the validity of helium preinjection as a means of simulation of transmutant helium production. Results for preinjected and single-ion irradiated samples were compared to samples irradiated with 3 MeV Ni/sup +/ and simultaneously injected with helium at a rate of 15 appM He/dpa (dual-ion irradiated samples). Preinjected samples exhibited bimodal cavity size distributions. Preinjected samples of solution annealed or solution annealed and aged material showed lower swelling than dual-ion irradiated samples. However, He preinjection in 20% cold worked samples showed greater swelling than dual-ion irradiated samples 9 figures, 1 table.
