Book Description
The behavior of helium in uranium and in several uranium alloys was studied metallographically after room temperature irradiation with alpha particles in a cyclotron, followed by various heat treatments. The observed gas bubbles were classified in two classes, differing in size, concentration, and mechanism of formation. These bubbles appear to resemble those resulting from fission product gases in neutron-irradiated uranium; the findings of this study seem to be applicable to the understanding of the factors affecting bubble formation and thus to the suppression of swelling in neutron-irradiated materials.

Book Description
The swelling of uranium and of a few selected uranium alloys on post-irradiation annealing was investigated by utilizing density measurements in conjunction with the observation of pores in the microstructures of annealed specimens. Specimens were irradiated to about 0.3 at.% burnup in a constrained condition at approximately 275 deg C and were subsequently pulse annealed. The amount of swelling was found to be less than 1% for U specimens that were pulse annealed up to 75 hr at temperatures below 550 deg C; the amount of swelling, however, increased considerably on annealing at temperatures between 550 and 650 deg C. Specimens pulse annealed up to 75 hr at 618 deg C decreased in density by approximately 18%. The swelling was accompanied by the formation of bubbles on grain boundaries in recrystallized regions. The observations suggest that recrystallization is a necessary prerequisite for pronounced swelling in the alpha phase.
