The Measurement of X-Ray Residual Stress in Textured Cubic Materials

Abstract

An X-ray diffraction procedure for measuring residual stress assumes a linear relationship between the d spacing and sin 2psi in isotropic materials. This study attempts to deal with the use of such a relationship in textured steel and aluminum using parallel beam optics. It was found that a phase difference occurs in the d spacing and the X-ray intensity of the CrK alpha diffraction peak with psi resulting in errors in computing the residual stress. Possible contributing factors are considered, such as systematic errors, specimen preparation, absorption, grain size, and the optical system employed.
