Abstract

The effect of post-irradiation annealing at 300°C for 50 hours on the microstructure and mechanical properties of CuCrZr irradiated to 0.3 dpa at 100°C has been evaluated. The post- irradiation annealing restores some ductility and work hardening to the material as well as lowers the yield strength, however it does not completely remove the effects of irradiation. A comparison of the microstructural features and mechanical properties in the as-irradiated condition and in the post-irradiation annealed case highlights the fact that the observed microstructure does not necessarily correlate with the changes in tensile behavior, most notably in the removal of the yield point and lowering of the yield stress after annealing.
