Effects Of Tial3 Addition In Ti--Al--C System On Combustion Synthesis Of Ti3alc2 Powders
Ti-Al-C体系中添加TiAl3对燃烧合成 Ti3AlC2粉体的影响

The experiment results show that the combustion products is TiC and very small amount of Ti3AlC2 if using the stoichiometric ratio of formula Ti3AlC2 and Ti, Al and C powders as raw materials. However, Ti3AlC2 become the main phase in the final product as adding intermetallic compound TiAl3 in the raw mixtures without changing overall stoichiometry. The amount of Ti3AlC2 is increased with increasing the amount of TiAl3 in the initial mixtures. The above experimental phenomena were also explained through thermodynamic and kinetic analysis.
