In situ synthesis of TiC from nanopowders in a molten magnesium alloy

The synthesis of in situ formed TiC/Mg(ZM5) composite utilizing the exothermic reaction of the preforms consisting of Al, C and Ti powders in molten magnesium was investigated. The result showed that the reactant particle size has a great effect on the reaction. For a nano-size Al and C, and micron-size Ti powders system, in situ TiC/Mg(ZM5) composite was fabricated successfully.
