FIELD: powder metallurgy. SUBSTANCE: method comprises steps of placing into a capsule a titanium getter in the form of a sponge and a steel powder; sealing the capsule; heating it and compacting up to a compaction degree of the powder, consisting (90-100)% of theoretical one, by upsetting with use of a drop hammer in an open die set; annealing the blank at 1000 C over 2-3 hours and subjecting it to hot forging for providing final dimensions. EFFECT: enlarged manufacturing possibilities, enhanced quality of blank due to increased stability of its mechanical properties, increased yielding of metal. 5 cl
