What are the other limitations of residual stress measurement using XRD data?
Dear K. Deenadayalan
Many sources of error may frequently be encountered in the applications of x-ray diffraction to stress measurement. Realizing this is important because too many cases of x-ray stress applications have been made where errors have been overlooked only to be spotted as anomalous data by an engineer perusing the data. This has caused x-ray diffraction techniques to be labelled as unreliable in many circles. The most common causes of error in stress measurement by x-rays are listed below. These do not include considerations such as counting statistics which must be considered in all x-ray diffractometry applications.
Stress Constant, Selection Diffractometer, Focusing Geometry, Diffracted Peak Location, Cold Working, Texture, Grain Size, Microstructure, and Surface Condition. To understand in detail the most common causes of error in X-ray stress measurement, I am attached below the standard book, which can give you a good background on what you are looking for.
