Grain Size Chart of Uranium,
Abstract
The metallurgist who is familiar with uranium is aware that the metallographic study of the metal has been complicated by certain factors. Of these factors, two, namely, the anisotropic crystal structure and the presence of the so-called beta 'ghost' grains, have made accurate and rapid grain-size determinations, by comparison with existing grain-size charts for other metals, difficult at best. With this in mind, an attempt has been made to devise a chart specifically for uranium. As the metal is observed metallographically by both polarized light and bright field illumination, all structures have been photographed using both methods of illumination. In the production of the desired grain diameters, the fabrications and heat treatments were made as nearly typical to those used in practice as was possible. The magnification used in photographing the structures was chosen because of its widespread use by those laboratories engaged in the metallographic study of the metal. It is hoped that this grain-size chart will prove of some value to those metallurgists who are involved in the study of uranium.
