Multifunctional Two- and Three-Dimensional Polycrystalline X-Ray Diffractometry

Indexed in: Chemical Abstracts, EBSCO.

A novel X-ray diffraction (XRD) theory is intensively revealed in this book. The theory will extend present XRD view from one dimension to two and three dimensions, enabling readers to see the ...

General Considerations

X-ray stress measurement method takes advantage of X-ray diffraction phenomena and is used to obtain the stress in metallic materials, ceramics and polycrystalline aggregates by measuring their lattice distortions. This method has salient features: a) the measurement is non-contact and non-destructive; b) not only the added stress but also the residual stress is measurable; c) exceedingly small portions (approximate 1mm2) in a thin layer (a few μm or less) of the sample are examined. This measurement technique is especially effective, such as....
