Abstract:
1. A process for the in-situ synthesis of titanium carbide (TiC) reinforced aluminum matrix composites, said process comprising the steps of: providing masses of aluminum, titanium and calcium carbonate powders; mixing the aluminum and titanium powders and blending the aluminum and titanium powders with the calcium carbonate; providing a high frequency induction heater (HFIH) at a high heating rate to thereby disassociate the calcium carbonate into carbon dioxide gas (CO providing a tube furnace with an inert atmosphere; and introducing the aluminum, titanium and carbon particles into the tube furnace at an elevated temperature under an inert gas atmosphere and forming in-situ TiC as a result of an exothermic reaction between titanium and carbon and between titanium aluminide and carbon and wherein the TiC particles have a spherical shape with a particle size in the range of 100 nm and 5 μm.
