Recent results on 3D characterisation of microstructure and damage of metal matrix composites and a metallic foam using X-ray tomography

High resolution X-ray tomography experiments were carried out at the European Synchrotron Radiation Facility in Grenoble as well as with a lower resolution tomograph at institut national des sciences appliquees in Lyon. 3D numerical images were collected which helped to study the microstructure and also the damage of different light materials. Recent results obtained with this technique are presented in this paper, concerning model Al/ZrO2 composites, Ti based continuous fibres reinforced composites and an Al foam.
