Abstract

L'invention concerne un alliage Mo-Si dans lequel le silicium est complètement dissous, caractérisé en ce qu'il renferme au moins un oxyde métallique en une quantité de 0.01% en poids à 1% en poids, et en ce que l'oxyde métallique présente à 1500°C, une enthalpie libre G inférieure à - 500 KJ/mol. L'invention concerne en outre un procédé de production des alliages Mo-Si correspondants, ainsi que des pièces métalliques frittées en tant que bagues de lubrification centrifuge.
