Description
The high pressure and high temperature (HPHT) behavior and phase stability of titanium-aluminium carbide (Ti2AlC) were investigated using X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron micrograph (SEM), and energy-dispersive X-ray analysis (EDXA). The results show that the decomposition temperature of Ti2AlC decreases against pressure. At pressures of 3, 4 and 5 GPa, the low temperature limits of phase segregation of the sample Ti2AlC lie between 1300 and 1200 deg. C, 1100 and 1000 deg. C, 900 and 800 deg. C, respectively. The decomposition products are identified to be titanium carbide and titanium aluminium
