The proposed method of nanopowder consolidation for the preparation of bulk billets by gas extrusion includes the sintering of a pressed piece in reducing atmosphere for the removal of oxide film from the surface of metal particles and hot pressing. The sintering in the reducing atmosphere is performed up to the attainment of closed porosity in the billet, and hot pressing is performed by extrusion in inert-gas medium by local heating of the deformation region to a temperature below the recrystallization temperature. The technical result is the development of the method for the manufacture of long metallic articles with nanocrystalline structure.
