TREATMENT METHOD OF FLAT WORKPIECES FROM METALS AND ALLOYS Russian patent published in 2013 - IPC C22F1/00 B21C37/02 

FIELD: metallurgy.

SUBSTANCE: treatment method of flat workpieces involves hot plastic deformation of a workpiece section as per a complex loading scheme using supports, on which there located is the workpiece, at the temperature of deformed section, which is required for obtaining the specified structure and properties in the workpiece material; with that, loading is performed by means of multiple cyclic alternating bend of the workpiece section between supports by means of forming elements, for example those located on both sides of the workpiece between supports with possibility of alternating action on the workpiece section between supports and forming elements by forces leading to deformation combining the tension and shear, and compression and shear, and after the loading the workpiece is flattened, shifted by the value of the deformed section, and loading is repeated.

EFFECT: implementation of a method for regulated crushing of structure of flat workpieces up to microcrystalline one.
