FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to production of high-density monolith billets from metal and alloy powders of micron and nanocrystalline dispersity. Powder metal produced by cryogenic grinding is degassed and compacted to 3D billet. Said billet is placed into container made from material with tensile strength making at least of said monolith billet powder material. Then, intensive plastic straining is effected by stepwise overall half-closed forging in three axes of orthogonal system to cause mode of deformation of simple shearing strain. Forging is carried out in several cycles to reach accumulated strain e>3 at temperature not exceeding that of powder material recrystallisation.
EFFECT: higher density and hardness.
