Abstract
- Abstract: We report on the in situ electrical resistance measurements of Ti2AlC under high pressure up to 6 GPa using four-probe method in a cubic large volume press. The resistance of Ti2AlC changes smoothly with pressure without sharp anomalies, which reveals no phase transformations. The resistivity decreases with increasing pressure. At pressures above 3.5 GPa, the resistivity decreases slowly with a pressure dependence of about . In addition, the resistivity was also measured at the process of decompression. The resistivity changes slowly with a pressure dependence of about at pressures above 2.5 GPa. These results are associated with the resistivity change with temperature and could confirm that the transition metal plays the dominant role in electrical transport. [Copyright &y& Elsevier]
