(EN) METHOD FOR PRODUCING A SACRIFICIAL BODY FOR PRODUCING ALUMINAL TITANIUM ALUMINIDE COMPOSITE BODIES
(FR) PROCEDE POUR LA PRODUCTION D'UN CORPS SACRIFICIEL EN VUE DE FABRIQUER DES CORPS COMPOSITES ALUMINE/ALUMINURE DE TITANE
Abstract
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung eines Opferkörpers aus einem Ausgangsgemenge zur späteren Herstellung eines Bauteils aus einem Al2O3/Titanaluminid-Verbundwerkstoff, ein Ausgangsgemenge sowie einen Opferkörper. Aus dem Ausgangsgemenge, dem neben Titan, insbesondere als Oxid, noch Kohlenstoff und/oder dessen Vorprodukte, Füllstoffe und Bindemittel beigegeben werden, wird ein Formkörper gepreßt. Der Formkörper wird bei einer Überführungstemperatur einer Temperaturbehandlung zur Bildung des druckstabilen Opferkörpers unterzogen. Hierbei wird der Füllstoff und ggf. auch der Binder thermisch entfernt. Der Opferkörper ist zur späteren Befüllung mit Aluminium und/oder einer Aluminiumlegierung unter Druck vorgesehen, wobei die Befüllung bei einer Befüllungstemperatur stattfindet, die oberhalb der Überführungstemperatur angeordnet ist und wobei die Materialien des befüllten Opferkörpers und das Aluminium durch eine Festkörperreaktion unterhalb der Befüllungstemperatur zu einem Al2O3/Titanaluminid-Verbundkörper reagiert werden.
(EN) The invention relates to a method for producing a sacrificial body from an initial mixture which is then used to produce a component consisting of an Al2O3/titanium aluminide composite substance. The invention also relates to an initial mixture and to a sacrificial body. In addition to titanium, preferably in oxide form, carbon and/or its intermediate products, fillers and binders are added to the initial mixture. A shaped body is then pressed from the initial mixture and subjected to heat treatment at a transition temperature in order to obtain a pressure-resistant sacrificial body. The filler and optionally, the binder are thermally removed during this process. The sacrificial body is provided under pressure for subsequent filling with aluminium and/or an aluminium alloy. The filling process takes place at a filling temperature which is higher than the transition temperature. The materials in the filled sacrificial body and the aluminium are reacted in a solids reaction below the filling temperature to form an Al2O3/titanium aluminide composite body.
(FR) 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.
