Abstract

Herein, we report on the thermal expansion and stability of V2AlC in the 25–950 C temperature range. The sample was heated in an Argon atmosphere in a quartz capillary and the thermal expansion was measured using a X-ray synchrotron radiation source. Up to the maximum temperature explored, there were no signs of decomposition or phase transitions. The temperature variation of volumetric thermal expansion is given by a=2.53(5)x10-5 +5.75(3)x10-9 T C-1. At 9.40x10-6 C-1, the thermal expansions along both the a and c lattice directions are quite comparable; in other words, there is little thermal expansion anisotropy in V2AlC.
