Abstract
L'invention concerne un procédé de fabrication de pièces en alliage par métallurgie des poudres. Ce procédé consiste à préparer à partir des constituants dudit alliage une poudre comportant une phase solide fusible à une température T1 inférieure à la température théorique de brûlure T dudit alliage puis à fritter sous charge ladite poudre à une température au moins égale à T1 , ladite température étant telle qu'une seule des phases de la poudre soit liquide. Application à la réalisation de disques ou d'aubes de turbines en alliage de nickel ou de fer.
