Abstract

"The preferential orientations produced in binary alloys of U-Si and U-Cr on plane sections perpendicular to the direction of heat flow by cooling from beta-phase temperatures were determined. The experimentally determined textures were presented using inverse pole figures. A definite and reproducible relationship was found to exist between the preferred orientation present at any position and the cooling rate which material at the position had experienced. It was found that the concentration of the alloying elements within the ranges studied had little detectable effect upon the observed relationship between the cooling rate and the resulting preferential orientation. It was postulated that the observed relationship between texture and cooling rate in material which had been cooled rapidly resulted from oriented growth of the alpha phase produced by a shear-type beta-to-alpha phase transformation. At lower cooling rates where the transformation became diffusion controlled, the texture was accounted for on the basis of the plastic deformation of the alpha phase due to stresses developed at the beta-to-alpha transformation interface"--Abstract, page ii.
