|Summary||Computed Tomography (CT) has become well established as a nondestructive technique for the inspection, evaluation and analysis tool in the industry. Images generated by CT have to be analyzed in order to reflect density variation in material by x-ray attenuation. In this work, we present the application of this technique for detecting, at mesoscopic scale, defects and variation of volume fraction generated by heterogeneous distribution of particles and porosity in Metal Matrix Composites (MMC). The fabrication technique for these materials was modified in order to produce samples with lot of defects. Tomographic tests were made with a medical scanner GE12000.
