METHOD FOR SHPERO-DYNAMIC MATERIAL TREATMENT Russian patent published in 2007 - IPC B21J5/06 C21D7/10 C22F1/00 

FIELD: pressure treatment of materials, particularly to obtain parts with predetermined service performance level by cold plastic deforming thereof.

SUBSTANCE: method involves arranging cylindrical billet in matrix interior on shpero-dynamic fluctuation module so that the billet is supported by pusher, wherein the module comprises cavity with main resonator located in the cavity; performing double-sided billet deformation from the opposite directions thereof, wherein from upper billet end the billet is deformed by applying rolling force thereto by means of die, from lower billet end the billet is deformed by applying summary pulsed force of shpero-dynamic fluctuation module and main resonator. Additional resonator is freely installed in module interior to apply additional percussion force to lower billet end during billet deformation.

EFFECT: provision of wavy plastic deformation and creation of "artificial intelligence" zones in billet.
