| 摘 要： | Ti、Al和C粉的燃烧合成实验结果表明,在Ti:Al:C=2:2:1体系中,添加TiC≤10wt.％时,燃烧产物中Ti3AlC2的含量与未添加TiC的相比,有大幅度增加;添加TiC≥20wt.％时,燃烧产物中Ti3AlC2的含量略有减少,而TiC的含量增多.从燃烧温度的角度探讨了TiC对燃烧合成产物相组成的影响.

| Abstract: | The combustion synthesis experiment results show that the amount of Ti3AlC2 in the combustion products is increased considerably by adding TiC (WTiC≤10wt. % ) with contrast to no addition of TiC if the molar ratio of Ti, Al, C is equal to 2:2:1 with using Ti, Al and C powders as raw materials. Content of Ti3AlC2 in the final product is decreased a little with the addition of TiC (WTiC ≤ 20wt. %), but TiC in the combustion products is contrary to it. The above experimental phenomena were explained through combustion temperature anal- |
