摘要
The stability of Ti2AlN at high pressure of 5 GPa and different temperatures of 700-1 600 degrees C was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) equipped with an energy dispersive spectrometer (EDS). Ti2AlN was found to be stable at temperatures as high as 1 400 degrees C under 5 GPa for 20 min, and was proved that it held better structure stability than Ti2AlC under 5 GPa through comparative experiments of Ti2AlN and Ti2AlC (representative compounds of M(2)AX phases (211 phase)). The reaction process at high pressure had some difference from that at ambient pressure/vacuum, and Ti2AlN directly decomposed to TiN and TiAl at 5 GPa and 1 500 degrees C for 20 min. Moreover, the mechanism of phase segregation was discussed. In addition, the behavior of Ti2AlN contacting with Zr at high pressure and high temperature (HPHT) was also studied.
