Abstract

L'invention concerne un procédé de préparation d'un métal, présentant une dispersion pratiquement uniforme de particules de charges dures, et une poudre métallique renforcée par dispersion, préparée par le procédé. Le procédé est caractérisé en ce que l'on effectue les étapes suivantes : mélange des particules d'un premier constituant métallique avec des particules d'oxyde, possédant une énergie libre de formation à 1 000 degrés C négative, au moins aussi grande que celle de l'oxyde d'aluminium, et avec un second constituant métallique différent, ledit premier constituant métallique appartenant au groupe forme par le nickel, le cobalt, le fer et leurs alliages, ledit premier constituant métallique présentant une taille moyenne de particules inférieure à 10 microns, ledit second constituant métallique présentant une taille moyenne de particules inférieure à 10 microns; et broyage desdites poudres pendant une durée suffisante pour obtenir de la poudre, présentant une dispersion pratiquement uniforme de particules de charges dures et des agglomérations hétérogènes d'au moins deux constituants métalliques, lesdits constituants métalliques pouvant être décelés par microscopie électronique.
