EXPERIMENTS TO EXAMINE THE CONTRIBUTION OF GAS ATOMS TO VOID FORMATION IN IRRADIATED METALS

[摘要] The use of vacuum melting has been employed to demonstrate that residual gases, especially hydrogen, strongly influence void nucleation of copper, copper binary alloys and various Fe-Cr-Ni base alloys during either neutron or electron irradiation. Void nucleation in nickel appears not to be strongly affected by residual gases, however. Solute-free and solute-bearing Fe-Cr-Ni alloys appear to respond differently to differences in gas content. When contamination of specimens with sodium occurs during neutron irradiation, void nucleation in both as-fabricated and vacuum-melted specimens is similar, suggesting that gas atoms re-enter the specimens during irradiation.
