[Allègement des structures dans les transports : le rôle de l'innovation en métallurgie]
Le paysage de la production d'énergie et de son utilisation est confronté à des défis importants dans le secteur des transports. Les deux principaux moyens de transport, automobile et aérien, sont principalement fabriqués avec des métaux. La nécessité de réduire leurs émissions de CO2 se traduit par une exigence majeure d'allègement, qui ne peut résulter que d'une action conjuguée d'amélioration des alliages et de la géométrie des pièces. Cette contribution discute certaines des stratégies pour l'allègement des structures basées sur la conception innovante d'alliages d'aluminium et d'aciers et sur les procédés innovants par fabrication additive.
The landscape of energy production and use is facing great challenges in the transportation sectors. The two main means of transportation, automobiles and airplanes, are mainly made from metals. The necessity of reducing their carbon emission translates into major stakes for weight reduction, which can only be the result of an interplay between improving the alloys and the part's geometry. This contribution discusses some of the strategies for structural weight reduction based on innovative alloy design in aluminum alloys and steels and on innovative processing by additive manufacturing.
