Swelling and mechanical property changes in neutron-irradiated cold-rolled type 316 stainless steel
Samples of cold-rolled Type 316 stainless steel were irradiated in EBR- II to a fluence of about 8 x 10 n/m (E greater than 0.1 MeV) at 500 and 600C. Three sample configurations were used--small sheet tensile samples, small right-circular cylinders for immersion density, and thin foils for transmission-electron microscopy (TEM). TEM revealed voids in the foils irradiated at both temperatures. Immersion density results, however, indicated swelling only in the sample irradiated at 600C. Considerable recovery and precipitation were observed in foils irradiated at both temperatures. Results of tensile tests on irradiated samples showed a decrease in yield strength and an increase in ductility compared to unirradiated controls. (auth
