Void Swelling of Copper and Copper Alloys Induced by Heavy Ion Irradiation

Source

Microstructures of Cu, Cu-5Ni and Cu-3.5Zn irradiated with heavy ions at 523 K to 773 K to a dose of 15 dpa were examined. The addition of nickel or zinc was shown to result in an upward shift of the peak void swelling temperature. Although the results are consistent with those of a previous fast neutron irradiation experiment taking difference in the damage rate into account, the microstructural processes seem not to be a simple shift of temperature.
