Abstract
The effect of neutron irradiation on the precipitation of helium atoms in copper has been studied at temperatures up to 425°c. At 160°c end 300°c no effect was observed. At 425°c the irradiated sample exhibited considerable precipitation around grain boundaries as compared to an unirradiated sample held at the same temperature. It is concluded that the additional vacancies introduced during the irradiation enhance the precipitation process. The resultant voids are equal in size to those obtained at higher temperatures in the absences of radiation.Keywords
