Book Description
Uranium undergoes permanent dimensional changes when thermal cycled in the alpha-temperature range without passing through any phase transformations. This deformation is attributed to the anisotropy of thermal expansion inherent in noncubic metals. Alpha uranium, which is orthorhombic, is especially susceptible because of its high anisotropy of thermal expansion. Uranium rods prepared by a wide variety of fabrication an'd heat-treat methods were thermal cycled between 100°C and 550°C. Observations were made on the effects of fabrication technique, heat treatment, and thermal cycling on the dimensions, surface roughening, microstructure, and preferred orientation of these rods.

Microscopic Observations of High Purity Uranium Subjected to Thermal Cycling

Book Description
The deformation of uranium upon thermal cycling produced results in microstructure very similar to those obtained in aluminum under creep conditions. The macroscopic elongation of uranium upon cycling may therefore be closely associated with creep relaxation phenomena; however, further work of a more quantitative nature will be required to more clearly define the mechanism producing actual macroscopic dimensional change.
