摘要：

Titanium carbide varying from 6.34 to 21.60 volume fraction was reinforced in to iron matrix by the direct reaction of pure titanium in molten Fe-C alloy. A simple casting technique has been developed successfully to improve the precipitation and distribution of titanium carbide particles in iron matrix. Lime powder is used as a protective layer on the molten metal to avoid oxidation of titanium during melting and casting. The thermodynamic and kinetic studies support the precipitation of TiC in molten Fe-C alloy at the reaction temperature, 1600 degrees C. The size and shape of the in-situ TiC particles depend on the amount of titanium present in Fe-C molten alloy.
