This book was released on 1973 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue life and crack growth rate comparisons have been made of irradiated and unirradiated specimens of Type 348 stainless steel as a function of total strain amplitude. Notched specimens were cycled at resonance in reverse bending in dry air at constant amplitude, and crack growth rates were determined from changes in resonant frequency of vibration. Neutron irradiation to a fluence of 1.5 x 1021 n/cm2 > 0.1 MeV produces approximately an order of magnitude increase in fatigue life at a total strain of 0.20 percent. At lower strains irradiated fatigue life appears to approach an endurance limit and the increase in life becomes very large. The effects on life are attributed to decreased crack growth rates in the irradiated material. Thus, the results in dry air indicate that the fatigue performance at 550 F (288 C) of thin-section reactor components of Type 348 stainless steel should not be reduced by irradiation characteristic of pressurized water reactors. The influence of water vapor on the fatigue characteristics of irradiated Type 348 stainless steel is being investigated in a separate study.

This book was released on 1975 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of high fluence fast neutron irradiation on the fatigue behavior, microstructure, swelling, and microhardness were evaluated for annealed Type 304 stainless steel which had attained fluences near 1.6 x 1023 neutrons (n)/cm2 (> 0.1 MeV) at irradiation temperatures from 370 to 470°C (698 to 878°F). Unnotched fatigue specimens remotely prepared from the irradiated material were cycled at resonance in reverse bending in air at constant amplitude at 427 and 593°C (800 and 1100°F). At 427°C, the fatigue life was found to be strongly dependent on irradiation temperature. A decrease in fatigue life from 2 x 105 to 1.1 x 104 cycles was seen with increasing irradiation temperature within the range investigated. For irradiation temperatures below approximately 427°C, the fatigue life was found to decrease with increasing fluence in the range from 1.3 x 1022 to 1.5 x 1023 n/cm2 (> 0.1 MeV). The fatigue behavior of specimens tested at 593°C was characterized by a similar irradiation temperature dependency. At 593°C, however, little effect of fluence was observed in the irradiation temperature range below 427°C. At both test temperatures the nuclear exposure produced an increase in fatigue life at irradiation temperatures below 450°C.

Download or read book Fatigue Behavior at 650 C of 20 cold worked Type 316 Stainless Steel Irradiated at 550 C in the HFIR written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Type 316 stainless steel in the 20%-cold-worked condition was irradiated in the High Flux Isotope Reactor (HFIR) and subsequently tested in fatigue. The specimens were irradiated at 550°C to damage levels of 8 to 12 dpa and transmutation helium levels of 300 to 500 at. ppM. Fatigue testing at 650°C revealed that cyclic life was not significantly affected by the irradiation. However, unlike the results of tests of the same material at 550°C, no endurance limit was observed. The absence of an endurance limit is interpreted in terms of thermal creep.
