Abstract

The effects of some compositional and processing variations on the irradiation-induced swelling of 20 percent cold-worked Type 316 stainless steel have been investigated. Bombardment by 5-MeV nickel ions was used to simulate the fast neutron irradiation which occurs in breeder reactor core components. Swelling in cold-worked Type 316 was found to be lowered by additions of silicon and molybdenum. Swelling was also reduced by increasing the solution-annealing temperature prior to the final cold-working operation.
