In situ synthesis of TiC/Mg composites in molten magnesium

Magnesium reinforced by in situ particulates was synthesized utilizing the self-propagating high-temperature synthesis (SHS) reaction of Al-Ti-C preforms in molten magnesium. The result showed that the preform preheat temperature has a great effect on the SHS reaction. For a preheat temperature of 450 degreesC, in situ TiC/Mg composite was fabricated successfully.
