摘要：

The paper presents irradiation creep data for V-4Cr-4Ti irradiated to 3.7 dpa at 425 and 600 degrees C in the HFIR-17J experiment. Creep deformation was characterized by measuring diametral changes of pressurized creep tubes before and after irradiation. It was found that the creep strain rate of the US Heat 832665 of V-4Cr-4Ti exhibited a linear relationship with stress up to similar to 180 MPa at 425 degrees C with a creep coefficient of 2.50 x 10(-6) MPa-1 dpa(-1). A linear relationship between creep rate and applied stress was observed below similar to 110 MPa at 600 degrees C with a creep coefficient of 5.41 x 10(-6) MPa-1 dpa(-1); non-linear creep behavior was observed above similar to 110 MPa, and it may not be fully accounted by invoking thermal creep. The bilinear creep behavior observed in the same alloy irradiated in BR-10 was not observed in this study. Published by Elsevier B.V.
