Determination of the Single Crystal Elastic Constants by Diffraction from a Cubic Polycrystal
Published

Roland deWit
Abstract
Using the theory of statistical continuum mechanics, closed expressions are derived for the diffraction elastic constants of a cubic polycrystal that is statistically homogeneous, isotropic, and disordered. By measuring these constants for several diffracting planes of a single polycrystal, the single crystal elastic constants are determined.
