Title: Influence of helium-injection schedule and prior thermomechanical treatment on the microstructure of Type 316 SS

Abstract

The influence of different helium-injection schedules on microstructure development Ni/sup +/ ion irradiated 316 SS at 625/sup 0/C is discussed. Injection schedules were chosen to (1) approximate the magnetic fusion reactor condition and (2) mimic the mixed-spectrum reactor condition. Dual-ion irradiation to 25 dpa produced strongly bimodal cavity size distributions in solution-annealed and solution-annealed and aged samples, whereas single-ion irradiation followed by dual-ion irradiation to the same dose produced a cavity size distribution with a substantial component of intermediate-size cavities. Dual-ion irradiation produced only very small cavities in 20% CW material, while single-ion followed by dual-ion irradiation produced some intermediate size cavities and greater swelling. 10 figures.
