“…This feature is known to develop along the drawing direction and become intensified with the increase of drawing strain [13,14]. The h1 1 0i texture of ferrite is also believed to play an important role in strengthening the steel wires [9,15,16]. In view of this, a intriguing hypothesis may be made here: By purposely introducing the h1 10i fiber texture of ferrite in pearlitic steel prior to cold drawing process, a marked improvement in structural integrity and in mechanical properties and thermal will be achieved.…”

“…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.

“…Different types of grain boundaries (low and high angle, special and random, equilibrium and non-equilibrium) generate during the SPD processes which significantly affect the material properties [49,50]. In addition, strengthening due to texture evolution in terms of its influence on the Taylor factor in SPD-ed materials has been widely investigated [13,[51][52][53][54][55][56][57]. Especially for commercial purity Al alloys, refinement of the grain and subgrain sizes as well as the production of dislocations [58] are known as the main sources of strengthening during the severe plastic deformation processes (the Hansen's modified Hall-Petch (HP) relationship [59]).…”

This paper reports the microstructure evolution, mechanical properties and strengthening mechanisms of a commercial purity Al alloy (Al 1350) after severe plastic deformation by a novel continuous method called ‘Equal Channel Angular Torsion Drawing (ECATD)’. Electron backscatter diffraction (EBSD) results revealed an inhomogeneous grain refinement including a large fraction of low-angle grain boundaries. After four passes, the microhardness increases from the initial value of 35 HV up to 44 and 62 HV at the centre and near to wire surface, respectively. A combination of high strength and ductility can be achieved based on the results of a Taguchi design of experiment (DoE) for mechanical properties. The strengthening occurs due to increment of the dislocation density, and development of mainly new low-angle grain boundaries.
