Title (EN) PROCESS FOR PRODUCING REINFORCED ALUMINUM-METAL MATRIX COMPOSITES
(FR) PROCÉDÉ DE PRODUCTION DE COMPOSITES À MATRICE MÉTAL-ALUMINIUM RENFORCÉS
Abstract:
(EN) A process for producing metallic carbide particulate reinforced aluminum alloy matrix composite comprises the following steps: a) providing a molten aluminum matrix maintained at a temperature in the range of 750°C to 1200 °C; b) pneumatically injecting a metal containing compound into said molten matrix to form an alloy melt; c) injecting a hydrocarbon compound into said melt, to generate in-situ carbon for reacting with said melt, to obtain molten alloy containing metallic carbide particulate; and d) casting and solidifying said molten alloy.
(FR) La présente invention concerne un procédé de production de composite à matrice en alliage d'aluminium renforcé par des particules de carbure métallique. La présente invention prévoit la génération in situ de carbone pour qu'il réagisse avec le composé contenant du métal dans la matrice d'aluminium fondu afin de produire les particules de carbure métallique. Un composé hydrocarboné est sélectionné en tant que source de carbone. Le procédé selon la présente invention permet d'introduire dans la matrice d'aluminium jusqu'à 20% de la matière de renforcement particulaire au carbure métallique.
