Abstract

Post-irradiation annealing studies indicate small defect clusters may be a potential contributor to IASCC. In this study, small defect clusters and their behavior during annealing are examined. A CP-304 SS alloy was irradiated with 3.2 MeV protons to 0.17 dpa at <75°C. The increase in hardness after 0.17 dpa at <75°C was greater than that after 0.55 dpa at 360°C, but dropped significantly after annealing at 350°C for short times, although, no dislocation damage was observed using transmission electron microscopy (TEM). For samples irradiated in a previous study at 360°C, the smallest dislocation loops and clusters were removed preferentially during annealing at 500°C for 45 minutes. Computer simulations of the annealing behavior were performed for the data from both sets of experiments in order to gain further insight into the nature of small clusters.
