Self-Consistent Diffraction Stress Analysis Method for Estimating Stress, Strain-Free Lattice Parameter and Composition of Solid Solutions

Abstract

Self-consistent diffraction stress analysis method is proposed for analyzing solid solutions. Owing to the feedback of the strain-free lattice parameter, it is possible to perform the proposed method even when the exact composition is unknown. Employing an example specimen of (111) fiber-textured palladium cobalt alloy film with different compositions, the validity of the proposed method is confirmed by comparing results with that of the conventional method. This convenient proposal expands the applicability of diffraction stress analysis.
