Abstract

L'invention concerne un procédé de fabrication de pièces forgées creuses, qui comporte les étapes suivantes :- réalisation d'un noyau en matériau perdu dont la forme correspond à la forme intérieure de la pièce à obtenir, à la déformation près subie lors du forgeage,- positionnement du noyau dans un moule de fonderie,- moulage d'un métal autour du noyau pour envelopper complètement le noyau en vue d'obtenir une ébauche (18),- étancher l'ébauche (18) de sorte que le noyau se trouve complètement isolé vis-à-vis de l'extérieur,- forgeage de l'ébauche (18) afin d'obtenir la pièce à la forme souhaitée,- et débourrage du noyau de la pièce pour obtenir la pièce forgée creuse.
