In vacuum of 0.0133 Pa, impact consolidation of the commercial tungsten powder with a size of particles of 6—10 microns is carried out at temperatures of 850, 1050, 1260, 1450, 1500, 1600, and 1640°C. The isothermal holding before consolidation was 20 min. The obtained samples with a diameter of 25—27 mm and height of $\cong$ 10 mm were cut on two parts, one of which was subjected to annealing at a temperature of 1600°C within the hour. The annealed and not annealed parts of a sample are cut on rectangular bars for determination of density, structure, and mechanical properties. As revealed, almost dense samples are fabricated at a temperature of 1640°C. At a temperature of consolidation of 850°C and 1450°C, the porosity of samples is equal 9.3 and 6.5%, respectively. Annealing of samples reduces porosity by 2%. On the samples compacted at high temperatures and on the annealed samples, the intensive growth of grains is observed. Consolidation at 1500°C leads to the double growth of particles, and consolidation at 1640°C leads to triple growth. Annealing of these samples in addition increases the size of grains by 2—3 times and, as a result, the initial size of particles increases almost by ten times.
