Elastic-strain tensor by Rietveld refinement of diffraction measurements

, 1998
A procedure to obtain all components of the elastic-strain tensor by simultaneous Rietveld refinement of diffraction patterns collected at different specimen orientations is described. The refined lattice parameters yield the hydrostatic strain component.
