Title (EN) A METHOD FOR FORMING HIGH STRENGTH ALUMINUM ALLOYS CONTAINING L12 INTERMETALLIC DISPERSOIDS
(FR) PROCÉDÉ DE FORMATION D'ALLIAGES D'ALUMINIUM DE HAUTE RÉSISTANCE CONTENANT DES DISPERSOÏDES INTERMÉTALLIQUES L12
Abstract:
(EN) A method and apparatus produces high strength aluminum alloys from a powder containing L12 intermetallic dispersoids. The powder is degassed, sealed under vacuum in a container, heated, consolidated by vacuum hot pressing, and extruded.
(FR) L'invention concerne un procédé et un appareil permettant de produire des alliages d'aluminium de haute résistance à partir d'une poudre contenant des dispersoïdes intermétalliques L12. La poudre est dégazée, scellée sous vide dans un récipient, chauffée, consolidée par compression à chaud sous vide et extrudée.
