Title (EN) ADDITIVE MANUFACTURING METHODS USING ALUMINUM-RARE EARTH ALLOYS AND PRODUCTS MADE USING SUCH METHODS
(FR) PROCÉDÉS DE FABRICATION ADDITIVE UTILISANT DES ALLIAGES D'ALUMINIUM/TERRES RARES ET PRODUITS FABRIQUÉS À L'AIDE DE TELS PROCÉDÉS
Abstract:
(EN) Described herein are additive manufacturing methods and products made using such methods. The alloy compositions described herein are specifically selected for the additive manufacturing methods and provide products that exhibit superior mechanical properties as compared to their cast counterparts. Using the compositions and methods described herein, products that do not exhibit substantial coarsening, such as at elevated temperatures, can be obtained. The products further exhibit uniform microstructures along the print axis, thus contributing to improved strength and performance. Additives also can be used in the alloys described herein.
(FR) Cette invention concerne des procédés de fabrication additive et des produits fabriqués à l'aide de tels procédés. Les compositions d'alliage selon l'invention sont spécifiquement sélectionnées pour les procédés de fabrication additive et fournissent des produits qui présentent des propriétés mécaniques supérieures par rapport à leurs équivalents coulés. L'utilisation des compositions et des procédés selon l'invention permet d'obtenir des produits qui ne présentent pas de grossissement substantiel, par exemple à des températures élevées. Les produits présentent en outre des microstructures uniformes le long de l'axe d'impression, ce qui contribue à améliorer la résistance et les performances. Des additifs peuvent également être utilisés dans les alliages selon l'invention.
