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.
