Estimation of single-crystal elastic constants from textured polycrystal measurements

A method for estimating single-crystal elastic constants given the elastic constants and texture of a polycrystal is outlined for hexagonal crystal symmetry. The method is based on the Voigt and Reuss polycrystal-average formulations. Sample calculations are detailed for titanium diboride and wire-drawn and rolled copper. The influences of possible sources of error on the estimation scheme are examined.
