Some Recent Results on Stresses in Thin Films and Precipitates.
Abstract
Diffraction remains the premier tool for sampling the residual stresses in materials non destructively, the only one capable of determining the entire stress tensor, and with few assumptions. The technique has kept pace with the needs of researchers in the area of multiphase materials; now, the stresses can be separated into macro and micro components. The deviatoric macro and micro stress components and hydrostatic macrostress can be measured without knowledge of the unstressed lattice parameter. Bond strength of film and fiber and the yield stress can be examined by cooling samples, and there are new developments that enable gradients to be determined.
