| Summary: | The purpose of the paper is the justification of the thesis on the definition of incomplete pre-recrystallization annealing as an independent type of heat treatment of solid binding wire. For that, the rod made of steels 50-70 was subjected to patenting in nitre bath and drawn with the total reduction of 65.8 %. Next, the wire was exposed to the short term forced tempering at 400-420oC. The parameters of the deformation and heat treatment of strong binding wire were determined, which provide tensile strength of about 1270-1520 N/mm2, tensile strength with knot not less than 9,5 unit kN, relative elongation not less than 5 %. It is expedient to classify the annealing of steel cold-deformed wire, providing a slight strength reduction (up to 5-10%) with a significant ductility increase (2-3 times), as incomplete pre-recrystallization annealing, with the introduction of this concept, based on the nature of the phase-structural transformations to the theory and technology of heat treatment. |
