註釋The effects of 1-hr anneals at 1000 and 1800 deg F on the mechanical properties of Type 347 stainless steel specimens taken from the ETR J-10 pressure tube after fastneutron (> 1 Mev) exposures of approximates 7.1 x 1021 nvt were studied. The pressure tube operated at a maximum temperature of approximates 750 deg F in a stressed condition. Testing was done at 75 and 750 deg C. Uniform elongations were increased from approximates 1% in the as- irradiated material to 15 and 25%, respectively, by the 1000 and 1800 deg F anneals. The 1000 deg F annealing appeared to produce a better combination of mechanical properties. The microstructure of unirradiated, as-irradiated, and postirradiation-annealed specimens were very similar except for two specimens inadvertently heated above 1800 deg F during annealing. (auth).
