The experiment results show that the main phase of combustion products is TiC under vacuum, and is Ti 3AlC 2 under Ar atmosphere with Ti:Al:C=2:2:1(molar ratio) in the Ti-Al-C system by using Ti, Al and C powders as raw materials.

• 实验结果表明 ,Ti:Al:C =2 :2 :1(摩尔比 )体系燃烧合成Ti3AlC2 的环境气氛若为真空 ,燃烧产物主要为TiC ,若为氩气 ,燃烧产物主晶相为Ti3AlC2 ;
