Abstract
Textures of metallic uranium rods were measured by neutron diffraction. From experimentally measured single and composite pole figures, the crystallite orientation distribution function (ODF) was determined by the harmonic method using a computer program developed for the fiber texture with orthorhombic crystal symmetry. The composite pole figures measured at overlapped peak positions of the diffraction pattern were assumed to be a linear combination of several neighboring single pole figures. The calculated results show that the harmonic method based on this conjecture well recovers the experimentally measured composite pole figures. Anisotropie physical properties such as thermal expansion coefficients and elastic constants due to the texture were evaluated by numerically averaging the second and fourth rank tensors with the calculated ODF, respectively.
