摘要：

Tensile and Charpy specimens of normalized-and-tempered ORNL 9Cr-2WVTa reduced-activation steel and that steel composition containing 2% Ni (9Cr-2VVVTa-2Ni) were irradiated at 376-405 degrees C in the experimental breeder reactor (EBR-II) to 23-33 dpa. Steels were irradiated in two tempered conditions: 1 h at 700 degrees C and 1 h at 750 degrees C. The mechanical properties before and after irradiation of the 9Cr-2WVTa-2Ni steel were quite similar to those of the 9Cr-2WVTa steel, indicating no adverse effect of the nickel. Neither of the steels showed excessive hardening or a large increase in ductile-brittle transition temperature. (C) 2007 Elsevier B.V. All rights reserved.
