Abstract

The temperature dependence of swelling for 20% CW Type 316 SS containing nominally 15 ppm He has been established using 5 MeV nickel ions; swelling was measured using standard transmission electron microscopy techniques. The damage rate of this experiment is roughly 103 times faster than fast reactor irradiation resulting in a shift in the peak swelling temperature of +115±25°C.

Swelling is studied in the temperature range of 475 to 725°C after doses causing up to 105 displacements per atom. The technique is experimentally verified as a valid simulation of fast reactor irradiation for temperatures up to 625°C when the appropriate temperature shift is applied.

Swelling in the cold worked steels is less than that previously reported for an annealed steel at all temperatures and doses studied. However, above 625°C thermal recovery of the cold work results in a swelling behavior that gradually approaches that of annealed steel as the temperature and dose are increased. Swelling occurs in the temperature range of 525 to ~725°C with a maximum swelling at 625°C for both annealed and cold worked steels.
