An attempt is being made to alter the starting microstructure of CuCrZr to produce a microstructure that is not as sensitive to overageing under irradiation as the prime aged condition. Different overageing conditions (600, 700 and 800 degrees C for 4 hours) have been examined in an earlier report, and in this report shorter overageing times at 600 degrees C have been examined. Overageing times of 1 and 2 hours resulted in a microstructure that is similar in overall precipitate size and density to that of the oxide dispersion in GlidCop Al25. These samples will be included in future irradiation experiments to examine the effects of irradiation on the mechanical and physical properties.
