The mechanically activated sintering process was adapted to synthesize titanium aluminum carbide (Ti3AlC2) at low temperature. A mechanically induced self-propagation reaction occurred by mechanical alloying of 3Ti/Al/2C powder mixtures. In addition to powder products, a large amount of rigor granules with a size of 0.5 ∼ 10 mm were produced. Fine powders containing Ti3AlC2, Ti2AlC and TiC were obtained. The granules composed of Ti3AlC2, Ti2AlC and TiC. Adding Sn may remove Ti2AlC and enhance the synthesis of Ti3AlC2. After Sn was added, the products only contained Ti3AlC2 and TiC. The Ti3AlC2 content of the powders and granules were 75 wt% and 88 wt%, respectively. The mechanically alloyed products were pressureless sintered at 900–1300°C for 2 h. Sintering of these products at 900 ∼ 1200°C yields samples containing over 95 wt% Ti3AlC2. The sintered powder compacts with high purity Ti3AlC2 had a fine organization. The lath Ti3AlC2 of the granules had a length of 10–20 𝜇m.

The combustion reaction of Ti–Al–C–N system was investigated by using Ti powders and one CN𝑥 precursor powder as reactant powder blends. The reactant powder blends ratio was adjusted to obtain different materials. The phase composition of the samples was investigated by X-ray diffraction (XRD). The microstructure of the samples was observed by scanning electron microscopy (SEM). The result showed that Ti2Al(C,N)–TiAl𝑥, AlN–Ti(C,N) and Ti3Al(C,N)2–TiC composites can be fabricated by changing the reactant powder blends ratio.
