Abstract:

The basic diffraction techniques for the stress tensor analysis are reviewed, with particular emphasis on what can be done without knowing the unstressed lattice parameterss. Examples are given of the residual stresses in thin films, how to measure the bonding and yield stress in composites and separating the micro and macrostresses to examine load sharing between phases. In this paper the term composite includes thin films on substrates, and steel, as well as other phase mixtures i.e. to include any arrangement where one phase has its properties affected by the presence of another.
