研究了在静高压条件下Ti₃AlC₂的热稳定性, 结果表明: 在不同压力(2、3、4和5 GPa)下, Ti₃AlC₂直接分解的最低温度在700--800℃, 反应的最终产物主要为Al₃Ti和TiC。具体的分解反应过程取决于压力的大小。

Thermal stability of Ti₃AlC₂ at static high pressure was dealt with in this paper. It was found that the lowest reaction temperatures of Ti₃AlC₂were all between 700 and 800^oC at pressures of 2, 3, 4 and 5 GPa, respectively, and the final products mostly were Al₃Ti and TiC. The decomposition reaction processes depended on the pressure.
