| Abstract |
For the analysis of the fiber-and sheet-type texture of materials with hexagonal crystal system, two computer programs, TXFIBH and TXSHTH, were developed based on Bunge`s series expansion method. The pole figures measured on Zircaloy-4 rod and sheet samples by neutron diffraction were analyzed to obtain the crystal orientation distribution functions and theoretical direct and inverse pole figures. Analytical errors were studied in terms of numbers of input pole figure and degrees of series expansion. Based on ODF, some discussions were made to understand the distinctive features of observed textures. |
