Beschreibung
Zusammenfassung:	A method of manufacturing a reinforced steel or aluminum part, such as a part for a vehicle, from a reinforced blank is provided. The method includes forming a reinforcement patch and joining the reinforcement patch to a base by an additive manufacturing process to form a reinforced blank. After the additive manufacturing process, the method can include forming the reinforced blank by cold forming, warm forming, or hot forming. The full surface of the reinforcement patch bonds to the base, which provides performance benefits compared to welded reinforcement patches. L'invention concerne un procédé de fabrication d'une pièce en acier ou en aluminium renforcée, telle qu'une pièce destinée à un véhicule, à partir d'une ébauche renforcée. Le procédé consiste à former une pièce de renfort et à assembler la pièce de renfort à une base par un procédé de fabrication additive pour former une ébauche renforcée. Après le processus de fabrication additive, le procédé peut consister à former l'ébauche renforcée par formage à froid, formage à chaud (170 °C à 230 °C) ou formage à température élevée (400 °C à 500 °C). La surface entière de la pièce de renforcement se lie à la base, ce qui fournit des avantages de performance par comparaison avec des pièces de renforcement soudées.
