METHOD FOR PRODUCING RESILIENT ELEMENTS USING METHOD OF ANISOTROPIC ORIENTATION OF NANOSTRUCTURE IN MATERIAL Russian patent published in 2014 - IPC C21D9/02 B21F35/00 C21D8/00 

FIELD: mechanical engineering.

SUBSTANCE: high-speed heating of a rod up to a temperature above the Ac₃ point of phase transformations, plastic deformation of the rod by screw compression with twisting in the direction of compression of the spring coil, instant hot coiling of the spring at a temperature above Ac₃ with immediate coil quenching and tempering, ensuring anisotropically oriented steel structure is carried out.

EFFECT: improvement of quality of springs and reduction of energy consumption.
