"The possibility of obtaining larger, perfect single crystals of alpha uranium by a modified strain-anneal method has been investigated. A -196°C tensile deformation was performed on pseudo single crystal rods which had been prepared by the phase transformation method. The specimens were subsequently annealed at 650°C.
It was found that by utilizing pseudo single crystals with a prescribed crystallographic orientation with respect to the tensile axis that recrystallized crystals of comparable size and perfection to those prepared by the grain coarsening method could be produced. Grain coarsening is the presently accepted process for preparing perfect single crystals of alpha uranium.
The higher purity of the perfect crystals prepared by the strain-anneal method described in this paper is definitely an improvement over the purity of the crystals produced by the complex grain coarsening technique, which requires intentional additions of foreign elements"--Abstract, page ii.
