OSTI ID:6843520
Miniature Charpy specimens of HT-9 in base metal, weld metal and heat affected zone (HAZ) metal conditions, and 9Cr-1Mo in base metal and weld metal conditions have been tested following irradiation in the High Flux Isotope Reactor (HFIR) at 55/degree/C to /approximately/5 and 10 dpa. All specimens conditions are found to have degraded properties (both DBTT and USE). 9Cr-Mo degraded more than HT-9 and weld material performed worse than base metal which performed worse than HAZ material. As a function of dose, property degradation was approximately linear, indicating that degradation response had not saturated by 10 dpa. 11 refs., 2 figs., 3 tabs.
