Electrical and thermal conductivities of a sample containing 96% of MAX-phase Ti3AlC2 and 4% of TiC were experimentally studied in the temperature range of 15–300 K. The maximum thermal conductivity is observed at approximately 75 K. As the temperature increases, the fraction of phonon heat transfer decreases from ∼90% at low temperatures to ∼40% at the room temperature.
