Abstract

In order to investigate the effect of the environment on the irradiation creep properties of highly purified V-4Cr-4Ti alloys, neutron irradiation experiments with sodium-enclosed irradiation capsules in Joyo and lithium-enclosed irradiation capsules in HFIR-17J were carried out using pressurized creep tubes (PCTs). It was found that the creep strain rate exhibited a linear relationship with the effective stress up to 150 MPa at 458 and 598 °C in the Joyo irradiation experiments. For HFIR-17J irradiation at 425 °C, the creep strain rate also exhibited a linear relationship with the effective stress up to 150 MPa. The activation energy of the irradiation creep and irradiation creep stress factor were estimated to be 46 kJ/mol K and 1-2, respectively. No significant difference in the irradiation creep behavior between liquid-sodium and liquid-lithium environments could be seen.
