Diffraction elastic constants of a cubic polycrystal

R. de Wit

Abstract: New expressions for the diffraction elastic constants are presented for a cubic polycrystal that is statistically homogeneous, isotropic and disordered. The results are an extension of the theory of statistical continuum mechanics and differ from a previous derivation given by Bollenrath, Hauk, & Müller [Z Metallkde (1967), 58, 76-82].
