FIELD: process for plastic working of metals, may be used in aerospace industry, as well as in mechanical engineering and instrument building.
SUBSTANCE: method involves deforming blank by twisting which is performed within zone restricted by individual matrices by pulling blank via through openings provided in said matrices and having sections corresponding to shape of blank profile. Blank has section different from round section. Part of blank disposed between matrices is preliminarily twisted.
EFFECT: improved physico-mechanical properties of elongated articles, increased efficiency, and high metal utilization coefficient.
