“…There is much research aimed at SPD methods of application in drawing. [ 14–18 ] The simplest in terms of implementation is the method described in the study by Kireev et al [ 14 ] Authors consider the use of reverse bending on cold drawn fittings without additional heating. The main advantages of this method are its continuity and its ability to be used to produce long products with enhanced mechanical properties.…”

A successful attempt to incorporate the advantages of severe plastic deformation (SPD) methods in the continuous drawing process for low‐carbon steel is demonstrated. The structural features are considered on different scale levels, using a wide range of methods. While combining shear deformation, which parallels the basis of SPD with the conventional scheme, the cyclic process of grain refinement could be reached. As a result, the plasticity becomes enhanced. At the same time, an important characteristic such as residual stress also has a positive influence on manufacturability; particularly, the existence of the compression stress after shear deformation. The peculiarity of the structure affects the behavior of both mechanical and physical properties (like density, plasticity). The application of drawing with shear (DSh) technology as based on SPD principles, the mechanical softening effect is observed, as is the healing of microvoids. Such positive affection gives the opportunity to increase the effectiveness of drawing technology through controlling plasticity (ductility). In addition, it is considered exhaustion of the plasticity resource (EPR). It is shown that in the case of multipass deformation, there is a parabolic dependence of the EPR measurement, and minimum damage is achieved using a specific combination of partial reductions.

“…One of constraints imposed upon the production of UFG wire is that the total output of the materilas produced by the listed SPD methods is measured by tens of kilograms and tons but the required capacity of wiredrawing production is hundreds of thousand tons.A possible solution of the problem of the long wire products can be application of drawing with shear. As may be supposed, an increase in the plasticity reserve of rods and wires allows cheapening and simplification of the production technique due to the abandonment of the intermediate anneal.In [1][2][3][4][5][6][7][8][9], different methods of severe plastic deformation of long metal billets of varied configuration are described. The works [5,6,9] are of special interest here.The authors of [5] analyze the application of sign-alternation twisting of cold-drawn furniture without an additional heating.…”

Donetsk Institute for Physics and Engineering named after А.А. Galkin NAS of Ukraine 72 R.Luxemburg Str., 83114, Donetsk, Ukraine 1 SPA «Donix», Donetsk, UkraineTo obtain the materials of ultrafine grain (UFG) structure, different methods of severe plastic deformation (SPD) with shear in both cold and hot state are used: equal-channel angular pressing, twist extrusion, and combination of these methods with succeeding rolling, upset, drawing etc. The application of these methods allows substantial increase in the strength of the material at certain conserved reserve of plasticity.However the mentioned combination of the methods can not be realized at wiredrawing production plants, whereas the last are very interested in new technological and operation characteristics of long-length wire products [1,2]. One of constraints imposed upon the production of UFG wire is that the total output of the materilas produced by the listed SPD methods is measured by tens of kilograms and tons but the required capacity of wiredrawing production is hundreds of thousand tons.A possible solution of the problem of the long wire products can be application of drawing with shear. As may be supposed, an increase in the plasticity reserve of rods and wires allows cheapening and simplification of the production technique due to the abandonment of the intermediate anneal.In [1][2][3][4][5][6][7][8][9], different methods of severe plastic deformation of long metal billets of varied configuration are described. The works [5,6,9] are of special interest here.The authors of [5] analyze the application of sign-alternation twisting of cold-drawn furniture without an additional heating. The main advantages of the method are continuous operation and possible application to the production of long products with enhanced mechanical properties. In [6], a method of plastic structure formation in the material of long billets is tested, and a facility of the realization is presented that is based on sign-alternating deformation within intersecting channels. The deformation zone is formed within the billet due to a shift of the symmetry axes of the channels combined with uniaxial tension. The presented method is intermittent, and the finite billets of several meters in length can be produced. The advantage of the method is formation of a fine grain structure. But the deforming block is even more complex than that in the case of [5]. Both the methods [5,6] do not permit production of the wire of small diameter.A drawing-based method of obtaining of UFG structure in long products is described in [9]. The main advantage is continuous operation and possible application to the large-scale drawing production. A drawback is labor intensity of drawing because a complex technical facility is used that requires disassembling and new installation in the course of replacement of wire drawing dies.The present paper reports the developed technique of drawing with shear aimed at enhancement of technological plasticity of low-carbon steels without thermal treatment.
