Abstract

L'invention concerne un produit de broyage d'un métal en poudre (P/M) et le procédé de fabrication de ce produit à base de métal réfractaire à faible teneur en oxygène (<400 ppm), ou d'alliages de celui-ci. Ce procédé consiste à utiliser un additif d'oxyde (tel que MgO, SiO¿2?, et Y¿2?O¿3?) dans la co-fabrication pour stabiliser la taille des grains du métal réfractaire selon les besoins des applications haute température. L'un de ces produits est une tôle à grains de faible taille qui contient des particules d'oxyde comme stabilisateurs de la taille des grains. Par ailleurs, ce produit présente de bonnes propriétés mécaniques, une faible teneur en oxygène dans les dérivés de fibres de métaux réfractaires de la poudre contenue dans le produit de broyage, et il se présente sous la forme de grandes pièces de tôle (dimensions latérales). Cette poudre de métal est compactée en un larget par différents procédés et peut peser 50 livres au minimum.
