A study has been made of the preferred orientation in uranium rods rolled to various reductions at 300°C and 600°C. The rods used for the 300°C final rolling were obtained from three groups which had been previously either rolled at 600°C, or rolled at 300°C and annealed at 550°C, or beta treated. The rods used for the 600°C final rolling were obtained from material previously beta treated. It was found that, regard-less of the starting material, the orientation obtained was the same if the reduction at 300°C was approximately 70% or greater. A considerable variation in orientation was observed in rods with lower reduction. The type of orientation developed by 600°C rolling is somewhat different from that obtained by 300PC rolling. Thermal cycling and thermal expansion data are also given for these rods.
