Elements of X-ray Diffraction
Prentice Hall, 2001 - Technology & Engineering - 664 pages
Intended to acquaint the reader with the theory of x-ray diffraction, the experimental methods involved, and the main applications. The book is a collection of principles and methods stressing X-ray diffraction rather than metallurgy. KEY TOPICS: The book is written entirely in terms of the Bragg law and can be read without any knowledge of the reciprocal lattice. It is divided into three main parts--Fundamentals; experimental methods; and applications. MARKET: Designed for beginners, not as a reference tool for the advanced reader.

While it has had some application to stress measurement in ceramics and rocks ,
its major use is the measurement of residual stress in metals and alloys , X - ray
diffraction , for example , has been used to measure stresses around a fatigue ...

This method is inherently destructive , even for the measurement of surface stress
, and slow . Part of the residuallystressed object is removed , by cutting or some
other method . This removal upsets the pre - existing balance of forces , with the ...
