  • Thermal stability of Ti2AlN-Al at high pressure is studied. Based on X-ray diffraction (XRD) and scanning electron microscopy (SEM), it was found that the thermal stability was mainly dependent on the temperature, but less on the pressure. When the pressure is 3, 4 and 5 GPa, the lowest reaction temperature of Ti2AlN-Al was between 500 and 600 ℃, and the decomposition products depended on temperature. When the temperature was up to 900 ℃, Ti2AlN-Al had completely decomposed and most of the final products were Al3Ti and TiN.
