Influence of the Mechanical Activation of Charge on the Structure and Phase Composition of Sintered Multicomponent Composites Based on Titanium

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.

Quasibinary System

On the principle of alloying modification of the same crystal structure compound, MoSi2-AlCr2quasibinary system alloys were prepared by mechanical activation and hot pressed sintering.The phase composition and crystal structure evolution were investigated by X-ray diffractometer(XRD).The results showed that the main phase composition of alloys were MoSi2and Mo(Si,Al)2,the crystal structure was gradually transformed from tetragonal C11bMoSi2to hexagonal C40 Mo(Si,Al)2. (Mo,Cr)(Si,Al)2phase has not found in alloys.
