Effects of interstitial solutes on the microstructures of self-ion irradiated vanadium
Vanadium and vanadium containing 0.1 percent C, 0.4 percent C, 1.0 percent N, and 1.0 percent O were irradiated with 3-MeV /sup 51/V/sup +/ ions in the temperature range 650 to 880/sup 0/C to a dose level of approximately 20 dpa. The results show that nitrogen is most effective in controlling the void swelling. Carbon and oxygen also suppress the swelling considerably when compared with unalloyed vanadium. Except for V-1.0 percent N, all compositions exhibit a fine platelet precipitate with (012) habit at 650/sup 0/C. In the case of vanadium-carbon alloys, this phase persisted even at higher temperatures. Vanadium and V-1.0 percent O showed fine precipitation on dislocations and void surfaces at 880/sup 0/C. V-0.1 percent C exhibited a metastable (013) carbide precipitate at 880/sup 0/C, whereas V-0.4 percent C showed equilibrium V/sub 2/C phase with some (012) precipitates. This (012) precipitation was irradiation induced and was dependent upon the carbon concentration. V-1.0 percent N did not show any evidence of precipitation over the entire temperature range.
