Application of X-ray microtomography to the microstructural characterization of...
Velhinho, A.; Fernandes, F. M. Braz; Ferreira, S. C.; Rocha, L. A.; Vignoles, G.; Cloetens, P.This paper provides a brief overview of the possibilities offered by X-ray computed microtomography, and particularly synchrotron radiation X-ray microtomography, regarding metal matrix composite characterization, emphasis being placed in the case of Al-based functionally graded materials. Examples are provided concerning the characterization of the reinforcement population, interfacial properties, in-situ tran...
Evaluation of SiC-particle connectivity in functionally graded Al/SiCp composit...
Velhinho, A.; Vignoles, G.; Cloetens, P.; Thibault, X.; Boller, E.; Fernandes, F. M. Braz; Rocha, L. A.; Botas, J. D.Reliability of functionally graded metal matrix composites (FGMMCs) for automotive components is still dependent on the detailed knowledge of the mechanisms of the microstructural build-up, for instance on the mechanisms leading to the distribution and relative positions of the reinforcing particles. In order to assess the influence of the SiC particle size on the 3-D inter-particle connectivity in functionally...
