A, Velhinho, Sequeira PD, Martins R, Vignoles G, Fernandes FB, Botas JD, and Rocha LA. "X-ray tomographic imaging of Al/SiCp functionally graded composites fabricated by centrifugal casting." Nuclear Instruments & Methods in Physics Research Section B-Beam Interactions with Materials and Atoms. 200 (2003): 295-302. Abstract02_-_nuclear_instr._and_methods_b_200_2003_295-302.pdf

The present work refers to an X-ray microtomography experiment aiming at the elucidation of some aspects regarding particle distribution in SiC-particle-reinforced functionally graded aluminium composites.
Precursor composites were produced by rheocasting. These were then molten and centrifugally cast to obtain the
functionally graded composites. From these, cylindrical samples, around 1 mm in diameter, were extracted, which were then irradiated with a X-ray beam produced at the European Synchrotron Radiation Facility.
The 3-D images were obtained in edge-detection mode. A segmentation procedure has been adapted in order to
separate the pores and SiC particles from the Al matrix. Preliminary results on the particle and pore distributions are presented.
