An investigation of void formation in /sup 58/Ni/sup +/ ion-irradiated dilute Ni-Be alloys has been initiated. The effects of the irradiation parameters, irradiation temperatures, irradiation dose and dose rate, and alloy composition on the irradiation microstructure of alloys containing 0.1, 0.3, and 0.7 at.percent Be bombarded at doses up to 30 dpa at temperatures of 425, 525, and 625/sup 0/C are being investigated. The results of the electron microscopy of these irradiations are presented and compared with a recently developed swelling theory which takes into account both interstitial trapping and radiation-induced solute segregation.
