Abstract

L'invention concerne un procédé pour la production d'un corps sacrificiel à partir d'un mélange initial permettant la fabrication ultérieure d'un composant constitué d'un matériau composite Al2O3/aluminure de titane, un mélange initial ainsi qu'un corps sacrificiel. A partir de ce mélange initial auquel ont été ajoutés, outre du titane, notamment comme oxyde, encore du carbone et/ou ses intermédiaires, des charges et des liants, un corps moulé est moulé par pression. Ce corps moulé est soumis, à une température de transformation, à un traitement thermique en vue de former le corps sacrificiel stable à la pression. A cet effet, la charge et éventuellement également le liant sont éliminés thermiquement. Le corps sacrificiel est destiné à être rempli ultérieurement d'aluminium et/ou d'un alliage d'aluminium sous pression, ce remplissage s'effectuant à une température de remplissage se situant au-dessus de la température de transformation. On fait réagir les matériaux du corps sacrificiel rempli et l'aluminium par une réaction à l'état solide à une température inférieure à la température de remplissage, pour obtenir un corps composite Al2O3/aluminure de titane.
