Synopsis

How materials behave under different conditions is key information for structural and mechanical engineers. The authors of this book shows how X-Ray tomography can be used as a very powerful tool to investigate the microstructure and behaviour of structural materials such as A1 and Ti based metal matrix composites, aluminium alloys and foams. The authors describe the technique and introduce the algorithms used for the reconstruction of the 3-D numerical images. The use of both synchrotron and X-Ray sources is illustrated.

Synopsis

For researchers dealing with structural materials, a key issue is the identification of the mechanisms responsible for the global mechanical behaviour of a material. Experimentally, this identification is quite an arduous task, carried out mainly through surface observations because most structural materials are opaque. The aim of this text is to show that X-ray tomography can be used as a very powerful tool to investigate the microstructure and the deformation mechanisms of structural materials. At the time of publication, this technique is the only one that can provide direct non-destructive images of the interior of a material. A global description of the technique is given, as well as an introduction to the algorithms used for the reconstruction of the 3D numerical images. An overview of new possibilities offered by third generation synchrotron X-ray sources is also presented with emphasis on the novel phase contrast technique which extends the field of classical X-ray tomography.

Finally, various examples illustrate how X-ray tomography can be used quantitatively for investigating the microstructure and behaviour of micro-heterogeneous structural materials such as AI and Ti based metal matrix composites, aluminium alloys and aluminium foams. The use of both synchrotron and laboratory X-ray sources is illustrated.
