Test results show that the notch sensitivity of 20% cold worked Type 316 stainless steel is dependent on irradiation temperature as well as test temperature. The temperature dependence becomes evident as the test temperature increases to 600/sup 0/C. At 232/sup 0/C, significant irradiation effects on the strength of 20% cold worked Type 316 stainless steel were observed. Irradiation hardening results from the introduction of various microstructural components which impede moving dislocations. For irradiation temperature less than or equal to 500/sup 0/C, the strength of irradiated 20% cold worked Type 316 stainless steel increases with increasing fluence up to a fluence of about 4 x 10 n/cm/sup 2/. Little additional hardening occurs beyond this fluence. The notch sensitivity changes from a notch strengthening at lower fluences to a notch weakening at a fluence of 7.8 x 10/sup 22/ n/cm/sup 2/ because of the inability of the material to relieve stress concentrations around a notch.
