Title (EN) CONVERSION PROCESS FOR HEAT TREATABLE L12 ALUMINUM ALLOYS
(FR) PROCÉDÉ DE CONVERSION POUR DES ALLIAGES D'ALUMINIUM L12 POUVANT SUBIR UN TRAITEMENT THERMIQUE
Abstract:
(EN) A method for producing high strength aluminum alloy containing L12 intermetallic dispersoids by using gas atomization to produce powder that is then consolidated into L12 aluminum alloy billets or by casting the alloy into molds to produce L12 aluminum alloy billets or by casting the alloy into directly useable parts.
(FR) L'invention porte sur un procédé de production d'un alliage d'aluminium de haute résistance contenant des dispersoïdes intermétalliques L12, à l'aide d'une atomisation gazeuse dans le but de produire une poudre, qui est ensuite consolidée pour donner des billettes d'alliage aluminium L12, ou par coulée de l'alliage dans des moules pour produire des billettes d'alliage d'aluminium L12, ou par coulée de l'alliage dans des pièces directement utilisables.
