The synthesis of the Ti2AlN-based material by means of the mechanical activation (MA) of the Ti‒AlN powder mixture in the planetary mill followed by the vacuum spark-plasma sintering (SPS). It was shown that the phase ratio AlN/Ti gradually decreases under mechanical activation. The data are given on the sample's phase composition, density and hardness after the SPS. The maximum Ti2AlN content value of 90 mass percent was achieved at the SPS temperature 1300 °C. The samples had the lowest porosity value of 1,9 % at the SPS temperature 1200‒1300 °C, the HV0,5hardness being close to 7 GPa.
