Abstract

L'invention concerne un procédé de moulage d'alliages à partir de poudres métalliques. Selon ce procédé, la poudre est protégée contre l'oxydation depuis sa formation initiale jusqu'a son moulage à la forme voulue, y compris pendant la fusion. Le procédé peut être mis en oeuvre rapidement, sans utilisation d'une refusion coûteuse et longue d'éléments tels que des barres moulées, et il évite la contamination et les défauts parfois rencontrés dans la matière qui a subi une refusion. Application au moulage d'éléments de turbine en superalliages.
