The results of investigation of the time and power parameters influence of high-temperature synthesis under pressure on the grain structure formation and strength properties of the Ni3Al intermetallic compound are presented and discussed. Dependences of the grain size in the intermetallic compound synthesized under pressure and its strength properties on the value of the preload on the initial powder mixture (3Ni + Al) and on the delay time of pressure application to the thermoreacting system were determined from the time of initiation of intermetallic compound formation volumetric exothermic reaction.

The article studies dependences of grain size in Ni3Al intermetallic compound synthesized under pressure in 3Ni+Al powder mixture in conditions of bulk exothermal reaction upon pre-pressure acting on the powder mixture and upon a delay time of applying pressure to a high-temperature synthesis product. It is proved that an increase in the pre-pressure on the parent powder mixture reduces the grain size, and an increase in the delay time increases the grain size in the synthesized intermetallic compound. Reducing the grain size from 10 to 1.75μm increases the strength of the intermetallic compound under pressure from 336 to 482 MPa (1.4 times).
