FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in making semis or rods and wire with ultra fine structure. Proposed method comprises deformation of long metal by drawing via two aligned and fixed tape dies with extra shearing by simultaneous alternating bending and twisting about metal lengthwise axis. Note here that metal axial speed and that of its rotation in area between fibers are kept constant.
EFFECT: expanded processing performances, higher physical properties.
