Title
(EN) METHODS FOR MAKING METAL ALLOY PRODUCTS
(FR) PROCÉDÉS DE FABRICATION DE PRODUITS EN ALLIAGE MÉTALLIQUE
Abstract
(EN)
The present disclosure relates to various embodiments of metal alloy and in particular a method for producing an aluminum alloy product comprising the steps of placing an additive manufacturing alloy feedstock in a pressurizable container, pressurizing the container to a predetermined pressure, selectively heating at least a portion of the additive manufacturing alloy feedstock, cooling the molten pool, and repeating the steps.
(FR)
La présente invention concerne divers modes de réalisation d'un alliage métallique et, en particulier, un procédé de production d'un produit en alliage d'aluminium comprenant les étapes consistant à placer une charge d'alimentation d'alliage de fabrication d'additif dans un récipient pouvant être mis sous pression, à mettre le récipient sous pression à une pression prédéterminée, à procéder au chauffage sélectif d'au moins une partie de la charge d'alimentation d'alliage de fabrication d'additif, à refroidir le bain fondu, et à répéter les étapes.
