As a result of calculating the influence of the volumetric effect of a chemical reaction on the porosity of the formation of the final product for the Al-Ni-Co system in vacuum, it is shown that the synthesized material will have a porosity of 7.6% more than the initial porosity P 0 of the initial sample.
To synthesize the SHS material with open porosity, the initial charge powders were mixed in a ball mill with Al 2 O 3 balls for 1 hour. The finished charge was poured into a graphite mold, which was placed in a vacuum furnace, and the temperature of the charge was brought to the autoignition temperature, then spontaneous combustion of the charge took place.
The phase analysis of the samples, carried out on a DRON-Zm diffractometer, showed the presence of the main phase (CoNi) 3 Al and free Ni. The pore size of the obtained samples was 2 - 2.5 ?m. The open porosity of the samples, estimated by the hydrostatic weighing method, was 42%.
