【 摘 要 】

Recovery of the capacity for plastic deformation by annealing previously cold-worked uranium plays a key role in the mechanism proposed for the cavitational swelling observed in irradiated uranium. Consequently, an investigation of recovery of yield strength was undertaken for unalloyed uranium and several selected alloys. During the course of this study, variations in the volume fraction of twins in the various specimens of unalloyed uranium suggested that twinning might be a mechanism of the recovery process. Results of four experiments in this study are described in this report.
