Irradiation Performance of Oxide Dispersion Strengthened Copper Alloys to 150 Dpa At 415°C
Results have been obtained on the post-irradiation properties of various oxide dispersion strengthened copper alloys irradiated from 34 to 150 dpa at 415°C in the Fast Flux Test Facility. The GlidCop™ alloys strengthened by Al₂O₃ continue to outperform other alloys with respect to swelling resistance and retention of both electrical conductivity and yield strength. Several castable ODS alloys and a Cr₂O₃-strengthened alloy show increasingly poor resistance to radiation, especially in their swelling behavior. A HfO₂-strengthened alloy retains most of its strength and its electrical conductivity reaches a constant level after 50 dpa, but it exhibits a higher residual radioactivity.
