Abstract
L'invention concerne un procédé de préparation par broyage de matériaux composites comportant une phase oxyde et une phase métallique. Le procédé de préparation des matériaux composites est caractérisé en ce que l'on mélange au moins un oxyde précurseur de la phase métallique et au moins un agent réducteur, précurseur de la phase oxyde, et en ce que l'on fait subir au mélange un broyage mécanique à haute énergie, - la quantité d'agent réducteur représentant de 90 à 110 % de la quantité stœchiométrique correspondant à la réaction de réduction de l'oxyde précurseur par l'agent réducteur. - la durée du broyage étant choisie de manière à réduire à l'état de métal, pur ou sous forme d'alliage, au moins 80 % des atomes de métal de l'oxyde précurseur.
