Title (EN) A METHOD FOR PRODUCING HIGH STRENGTH ALUMINUM ALLOY POWDER CONTAINING L12 INTERMETALLIC DISPERSOIDS
(FR) PROCÉDÉ DE PRODUCTION DE POUDRE D'ALLIAGE D'ALUMINIUM HAUTE RÉSISTANCE CONTENANT DES DISPERSOÏDES INTERMÉTALLIQUES L12
Abstract:
(EN) A method for producing high strength aluminum alloy powder containing L12 intermetallic dispersoids uses high pressure gas atomization to effect cooling rates in excess of 103°C/second.
(FR) L'invention concerne un procédé de production de poudre d'alliage d'aluminium haute résistance contenant des dispersoïdes intermétalliques L12. Le procédé selon l'invention utilise l'atomisation par gaz haute pression pour obtenir des vitesses de refroidissement supérieures à 103 °C/seconde.
