Abstract

To understand the effects of temperature change on pure vanadium and four vanadium model alloys (V-5Cr, V-5Ti, V-4Cr-4Ti, V-4Cr-4Ti-0.1Si), neutron irradiation was performed in high flux isotope reactor. The specimens were irradiated for a total of 8 irradiation cycles, which resulted in 4 dpa. Each irradiation cycle consisted 0.05 dpa at 498 K, followed by 0.45 dpa at 613 K. After the irradiation the TEM samples were electro-polished and examined by electron microscopy. The microstructures of the samples were compared with those of the same alloys, which were continuously irradiated at 613 K.
