Known harvesting for the production of parts with a specified level properties by precipitation with subsequent testing.

Disadvantages of procurement the following:

it is impossible by running the end of the workpiece placed on the support, to translate the workpiece in a state of dynamic instability and form in marching paramagnetic (non-magnetic) material, the combination of mutually exclusive features, such as hard magnetic and soft magnetic properties of the local arrays of metal parts, while maintaining the paramagnetic volume of metal with high elastic and corrosion resistant properties;

- diffusion activity of the surface layers of metal parts does not ensure its stable operation under conditions of ultra-low pressure biologically and chemically active environments and cryogenic temperatures;

it is impossible in the process of deformation of the workpiece penetration fur the mechanisms of plasticity (mod rotational ductility) to micro-level with the aim of forming a structural-informational field in the material details and long-term storage of information about the laws of loading the workpiece material at its deformation;

it is impossible to implement deformation mechanismy vortex of energy during the whole process (prototype).

The current task is to create in the material mode of deformation resonance, ensuring implementation of the wave nature of plasticity in the form of rotational modes of plasticity.

The solution is achieved by the fact that the workpiece is made of pre-shaped in the form of a cylinder with an annular flange, the size of which is determined by the expression:

where H is the height of the profiled blanks, mm;

h - the height of the lower part of zatowka, mm;

in - diameter annular flange, mm;

the thickness of the annular flange, mm

and intended for placement between the matrix and svetodinamicheskimi fluctuation deforming module with gaps, and the gap between the flange and the matrix exceeds the gap between the flange and the fluctuation deforming module.

The workpiece is represented by graphic material, in which figure 1 is blank before shaping; figure 2 is the same at the stage of onset of deformation response.

The workpiece 6 is placed on the cradle 4 fluctuation of module 3 is installed in the matrix 2 on the pusher 5, the annular flange is placed between the fluctuation module 3 and the matrix 2. After this is about producing a regulated draught of the workpiece 6 by the punch 1 and the subsequent forging, that you are carrying out the extrusion of the material of the annular flange of the workpiece 6 in the annular gap between the matrix 2 and 4 lodgement, providing an air gap between the bed 4 and the annular flange of the workpiece 6, and the gap between the latter and the matrix 2.

Fluctuations fluctuation module 3 bed 4 in the final stages of deformation of the workpiece 6 passes in a state of dynamic instability, through the local pulse effects on the peripheral part of the extruding metal annular flange of the workpiece 6 in a state of deformation of the resonance. The presence of spontaneous resonance condition Logement 4 and the occurrence of resonance oscillations peripheral annular sections of the extruding metal annular flange of the workpiece 6 is to create conditions for the realization of the wave mechanisms of plastic deformation - rotational modes (mechanisms) plasticity that enables the penetration of advanced plastic deformation by crystallographic (atomic) level, i.e. the implementation of nanoeffects. Rebuilding the original crystallographic structure causes a qualitative change in the original delicate structural properties of the material of workpiece, which illustrates the phenomenological character of the course of plastic deformation in the conditions of simultaneous realization of the mechanism of deformation of the resonance in the system of procurement-fluctuation module.

Preparation for svetodinamichesky treatment of materials by placing between the matrix and svetodinamicheskimi fluctuation deforming module and subsequent spinning, characterized in that it is made of pre-shaped in the form of a cylinder with an annular flange, the dimensions of the workpiece defined by the expression:

where H is the height of the profiled blanks, mm;

h - the height of the lower part to the level of the annular flange, mm;

b - diameter of annular flange, mm;

the thickness of the annular flange, mm,

the annular flange is made of the conditions for placing it between the matrix and svetodinamicheskimi fluctuation deforming module with gaps, and the gap between the annular flange and the matrix exceeds the magnitude of the gap between the annular flange and svetodinamicheskimi fluctuation deforming module.
