Abstract

In an earlier experiment it was shown that titanium additions tended to suppress swelling of American Iron and Steel Institute (AISI) 316 alloys in the annealed condition. Evidence is presented to show that a similar effect occurs in the cold-worked condition in both the Experimental Breeder Reactor (EBR-II) and the Fast Flux Test Facility (FFTF). The titanium-modified steels owe their improved swelling resistance not only to their titanium additions but also to small but significant changes in nickel, chromium, silicon and phosphorus levels.
