Application of EBSD to analysis of microstructures in commercial steels

Abstract: Electron backscatter diffraction (EBSD) is a very powerful technique for microstructural characterisation and analysis of crystalline materials. Many of the structural parameters that control the properties and performance of the material can be derived from EBSD data, e.g. grain size, phase constituents, mechanical anisotropy and residual strain. This should make EBSD a valuable tool to control and develop microstructures of commercial metallic materials but technique has mainly been used in basic research at universities and not to the same extent for research and development in industry. The development in scanning electron microscopes and EBSD equipment in recent years makes it possible to measure 'difficult' structures, e.g. with higher dislocation content, but can it manage the complexity of the structures of commercial materials and achieve reliable data? During 2004 an EBSD round robin test on industrial metallic materials was coordinated by KIMAB to test the current status of the techniqu...

An introduction to three-dimensional X-ray diffraction microscopy

Abstract: Three-dimensional X-ray diffraction microscopy is a fast and nondestructive structural characterization technique aimed at studies of the individual crystalline elements (grains or subgrains) within millimetre-sized polycrystalline specimens. It is based on two principles: the use of highly penetrating hard X-rays from a synchrotron source and the application of `tomographic' reconstruction algorithms for the analysis of the diffraction data. In favourable cases, the position, morphology, phase and crystallographic orientation can be derived for up to 1000 elements simultaneously. For each grain its average strain tensor may also be derived, from which the type II stresses can be inferred. Furthermore, the dynamics of the individual elements can be monitored during typical processes such as deformation or annealing. A review of the field is provided, with a viewpoint from materials science.
