| Abstract |
In the present study, fatigue strength of corroded nickel was examined after irradiation in a TRIGA-II reactor. Before the fatigue test, the samples which has been placed in distilled water were irradiated with the total neutron dosage of 4.6×10^(18) nvt (1.6×10^(18) nvt of fast neutrons and 3.0×10^(18) nvt of thermal neutrons) for ten months. The experimental result showed that the irradiated samples decrease about 10% in fatigue strength as compared to the control samples. This may be due to the formation of fatigue cracks at the grain boundaries caused by intergranular corrosion. |
