Abstract : This article researches XD (exothermic dispersion) technology syntheses of TiAl alloy and TiC/TiAl composite materials. In conjunction with this, it probes the synthetic reactive mechanisms. Results clearly show that it is possible to use--in the vicinity of the melting point of aluminum--XD techniques to prepare TiAl alloys as well as TiC/TiAl composite materials reinforced with TiC particles as well as that thermopositive reactions between Ti-Al powders promote the synthesis of TiC. TiAl alloy is composed of TiAl+Ti3Al phases, and TiC/TiAl composite materials are composed of TiC+TiAl+Ti3Al phases.
