Ductile fracture of metals is accompanied at the microscopic scale with the appearance of damage, in the form of small cavities. Damage progress is divided into three distinct and consecutive phases: initiation, growth and coalescence. This article illustrates the use of three-dimensional nondestructive imaging to study this damage development. Two techniques, mainly based on the attenuation of X-rays are now used for this type of studies at high resolution: tomography and laminography. The interest of laminography is that samples with larger dimensions (in the form of sheets) than the conventional tomography ones can be used. Examples of images obtained with the two techniques, as well as quantification using X-ray tomography, are presented.
La rupture ductile des métaux est accompagnée du processus microscopique dʼapparition dʼendommagement, sous forme de cavités de dimension micronique. Cet endommagement est décomposé en trois phases distinctes et consécutives : lʼamorçage, la croissance puis la coalescence. Cet article recense et illustre lʼutilisation de lʼimagerie tridimensionnelle non destructive pour lʼétude microscopique de cet endommagement. Deux techniques basées sur lʼabsorption des rayons X sont maintenant utilisables à haute résolution : la tomographie et la laminographie. La laminographie présente lʼintérêt dʼautoriser lʼutilisation dʼéchantillons de grandes dimensions (plaques) comparées aux petites éprouvettes de tomographie habituelles. Des exemples dʼimages obtenues à lʼaide de ces deux techniques ainsi que les méthodes de quantification de lʼendommagement par traitement dʼimage dans la cas de la tomographie sont présentés.
