Using a synchrotron radiation source and a diamond anvil cell, we measured the pressure dependencies of the lattice parameters of two Ga-containing polycrystalline MAX phases: Ti{sub 2}GaN and Cr{sub 2}GaC. The bulk moduli were calculated to be 189 {+-} 4 and 188 {+-} 5 GPa, respectively. Up to a pressure of about 50 GPa, no phase transformations were observed. Ti{sub 2}GaN compresses more easily along the c-axis, while Cr{sub 2}GaC compresses equally in both directions.
