Abstract

C. High pressure C. X-ray diffraction
The lattice parameters of Ti 2AlN and Ti 2AlC powders were measured as a function of pressure up to ≈50 GPa, using a synchrotron radiation source and a diamond anvil cell. No phase transformations were observed. As for most related layered carbides and nitrides, such as Ti 4AlN 3 and Ti 3SiC 2, the compressibilities of Ti 2AlN and Ti 2AlC along the c-axes are larger than those along the a-axes. The bulk modulus of Ti 2AlC at 186±2 GPa, is ≈10% higher than that of Ti 2AlN at 169±3 GPa.
