Triaxial Measurement of Residual Stress After High Feed Milling Using X-ray Diffraction

Depth-resolved residual stress evaluation from X-ray diffraction measurement data using the approximate inverse method

The paper deals with the depth determination of residual stress states from diffraction data. First an historical overview of the known approaches is given. Then we apply the approximate inverse method to this problem. This method is known to be very efficient and stable with respect to noise-contaminated data. It is even possible to prove convergence and it allows an error estimate of the calc...

Recent Advances in the Measurement of Residual Stress by X-Ray Diffraction

Crystallite Size Measurement Using X- Ray Diffraction

Mike Meier University of California, Davis September 13, 2004 Figure 1. FEG-SEM image of nanosized aluminum oxide powder. Note the magnification and the size of the micron bar. Also note how the smaller particles and the edges of the larger particles appear to be somewhat transparent. This is because much of the 5 kV electron beam can pass through these thinner parts of the particles. CRYSTALLI...

Depth dependence of residual strains in polycrystalline Mo thin films using high-resolution x-ray diffraction

The magnitude of the stress in a thin film can be obtained by measuring the curvature of the film–substrate couple. Crystal curvature techniques yield the average stress throughout the film thickness. On a microscopic level, the details of the strain distribution, as a function of depth through the thickness of the film, can have important consequences in governing film quality and ultimate mor...

Detection of breast cancer using non-invasive X-ray diffraction technique of hair: A preliminary study

Background: An early diagnosis of breast cancer relates directly to an accurate treatment plan and strategy. Early detection of breast cancer before its development would be a significant reduction of morbidity and mortality rates. The aim of this preliminary study is to investigate the sensitivity of Wide Angle X-ray diffraction (WAXRD) method on women hair samples of healthy and breast cancer...
