Effect of nickel content on the aging and irradiation response of impact properties of 9 Cr-1 MoVNb and 12 Cr-1 MoVW in the absence of internal helium effects

  • 1. Oak Ridge National Lab., TN

Description

The objectives of this study are to provide information on the radiation-induced degradation of impact properties of high chromium ferritic steels at moderate irradiation doses. It concurrently examines the viability of simulating helium effects in these engineering alloys by adding nickel and irradiation in a mixed spectrum reactor. Impact testing was completed on aged and EBR-II irradiated 9 Cr-1 MoVNb and 12 Cr-1 MoVW steels, each with and without small additions of nickel. Only limited property changes resulted from aging or irradiating to 12 dpa in the temperature range of 4500C to 5500C. Irradiation of the 12 Cr-1 MoVW at 3900C with and without nickel produced severe degradation of impact properties. Nickel additions affected the unirradiated material properties, but subsequent radiation-induced changes were similar regardless of nickel content. 7 references, 12 figures, 4 tables
