Welded joints of stainless steel DIN 1.4948, which is similar to AISI Type 304, have been irradiated at 723 and 823 K up to fluences of 1 X 10/sup 23/ neutrons (n) X m/sup -2/ and 5 X 10/sup 24/ n X m/sup -2/ (E>0.1 MeV). Tension and creep tests show considerable irradiation embrittlement, depending on fluence, test temperature, and strain rate. Creep strain values at 823 K reduce to 0.3 percent. The embrittlement is attributed to helium promoted intergranular fracture of the parent metal, the helium being formed mainly by the /sup 10//BETA/reaction. Low-cycle fatigue tests show considerable scatter (standard deviation 25 percent) of the fatigue life due to weld inhomogeneities, and therefore no significant difference between irradiated and unirradiated welded joints could be observed. Fracture is located in the weld.
