X-RAY DIFFRACTION RESIDUAL STRESS TECHNIQUES Paul S. Prev y, Lambda Research, Inc. GENERAL USES Macrostress measurement Nondestructive surface RESIDUAL STRESS measurement for quality control. Determination of subsurface RESIDUAL STRESS distributions Measurement of RESIDUAL stresses associated with failures caused by fatigue or STRESS corrosion Microstress measurement Determination of the percent cold work at and below the surface Measurement of hardness in steels in thin layers EXAMPLES OF APPLICATIONS Determination of the depth and magnitude of the compressive layer and hardness produced by carburizing steels Investigation of the uniformity of the surface compressive RESIDUAL stresses produced by shot peening in complex geometries Measurement of surface RESIDUAL stresses and hardness on the raceway of ball and roller bearings as functions of the hours of service Study of the alteration of RESIDUAL STRESS and percent cold work distributions caused by STRESS -relieving heat treatment or forming Measurement of surface and subsurface RESIDUAL stresses parallel and perpendicular to a weld fusion line
