A device for electro-plasticization of the metal billet and its subsequent deformation [Magazine "die Forging production", 1985, No.1, p.29-31].

The disadvantages of the known devices are:

- significant energy consumption of the process of plasticization of the metal of the workpiece due to the need for guidance on her series of pulses of electric current of high current density in the stream (~108 a/m2);

- the inability in the process of deformation of the workpiece to implement the wave nature of plastic deformation in the form of plastic rotors (vortices), penetrating to nanorover (10-9 m) of the metal workpiece and generates a regulated field compressive stresses forming in the metal pipe after the flexible pushing so-called "artificial intelligence".

The task for us is Vashego of the invention is to develop a device, allows early processing of the workpiece to clear the metal from earlier (vortices) in nanorover (10-9 m) of the metal billet and the formation of arrays of metal fibrous structure of the spiral geometry with "artificial intelligence".
