Abstract
The synthesis of a Ti2AlN-based material by mechanical activation (MA) of a Ti–AlN powder mixture in a planetary ball mill followed by vacuum spark plasma sintering (SPS) is investigated. It was shown that the AlN/Ti ratio gradually decreases under mechanical activation. Data on the sample’s phase composition, density and hardness after SPS are given. The maximum content of Ti2AlN at 90 wt.% is achieved at SPS temperature of 1300°C. The lowest porosity of samples at 1.9% is achieved at SPS temperature of 1200 – 1300°C, and the hardness HV0.5 in this case is close to 7 GPa.
