Résumé
Abstract

Les récents développements de sources synchrotron plus puissantes ont apporté une amélioration considérable des performances en imagerie X. Ceci sʼest traduit par une augmentation continue de lʼimpact scientifique des expériences effectuées avec une source synchrotron dans de nombreux domaines de recherche sur les matériaux, et en particulier lʼétude de la solidification. Il est bien établi que lʼimagerie X est une méthode de choix pour les études in situ et en temps réel de la formation des microstructures de solidification dans les alliages métalliques, avec des résolutions spatio-temporelles pertinentes. Dans cet article, nous présentons des résultats illustrant les capacités actuelles de lʼimagerie X synchrotron dans de ce domaine de recherche, chacun dʼentre eux utilisant des techniques différentes (radiographie, topographie et tomographie X). Ces résultats démontrent le fort potentiel de ces techniques dʼanalyse pour lʼinvestigation de phénomènes dynamiques en science des matériaux.

Recent developments of more powerful synchrotron sources have led to vast improvements in the performance of X-ray imaging. This is manifested by a continuous increase in the impact of synchrotron experiments in many research areas on materials, in particular solidification science. X-ray imaging has been established as a method of choice for in situ and real-time studies of solidification microstructure formation in metallic alloys, with spatio-temporal resolutions at the scales of relevance. In this article, we present illustrative results of the current capabilities of synchrotron X-ray imaging in this field of research, each of them using different X-ray techniques (radiography, topography and tomography). Those results demonstrate the high potential of these techniques for the investigation of dynamical phenomena in materials processing.
