Calculation of Single-Crystal Elastic Constants for Cubic Crystal Symmetry from Powder Diffraction Data
Thomas H. Gnaupel-Herold, Paul C. Brand, Henry J. Prask
In this work a method is developed that allows the computation of the single- crystal elastic constants for crystals of cubic symmetry from the diffraction elastic constants. The diffraction elastic constants can be obtained by measuring the hkl-dependent lattice strain response to an applied stress. Because of their hkl dependence they represent, partially, the anisotropic nature of the single-crystal elastic constants. The computation of the single-crystal elastic constants is carried out by a least-squares refinement which fits the calculated diffraction elastic constants to the measured ones.
