“…Fine (300 μm) meshes were applied on the surface area to inspect the complex deformation behavior. The friction factor of 0.1 was selected for numerical simulation according to the previous investigations [41][42][43]. Other parameters, e.g., drawing speed, die angle and reduction per pass, for numerical simulation were kept the same as the actual experimental conditions shown in Table 2.…”

“…The wire was assumed to be an isotropic material in this simulation, because hot-rolled steel was used as an initial specimen for the wire drawing test. A shear friction coefficient of 0.1 was selected for the wire-die interface; this was based on previous investigations [38][39][40]. To save on computational cost, half of the geometry was modeled because of the symmetrical constraints of the drawn wire.…”

The effect of changing the strain path on texture development, twin kinetics, and mechanical properties in twinning-induced plasticity steel was investigated to understand twinning behavior in more detail. Among the various plastic deformation processes, the wire drawing process was selected to achieve the aims of the study. Specimens of cold-drawn TWIP steel wire under the same effective strain but with different crystallographic textures were successfully fabricated using the effect of the wire drawing direction. Electron backscatter diffraction results showed that the drawn wires using both unidirectional (UD) and reverse-directional (RD) wire drawing processes were characterized as duplex fiber textures of major <111> and minor <100>. It was found that the RD wire had a higher fraction of <111> component at both the center and surface areas compared to the UD wire, because the metal flow of the RD wire was beneficial for the development of a <111> orientation. The pronounced <111> crystallographic orientation of the RD wire activated the twinning rate and geometrically necessary dislocation density, leading to an increase in strength but a decrease in ductility. The strain path is as important as the amount of strain for strengthening the materials, especially those that are deformed by twinning.

“…Despite the limitations in tension stress in drawing base methods, the processing of very long samples in materials with high formability (such as carbon steel) has been performed in the SD process. 141) In continuous processes such as ECAP conform, ECAR and ARB, since the pushing or dragging of the sample are performed by rollers and the sample is forced into the deformation area, there is no need for pull/push forces to the sample at both sides of the deformation zone. Therefore, the workability is almost higher than the earlier example and it could produce a very long sample.…”

Severe Plastic Deformation (SPD) processes have been extensively investigated in the last 30 years to facilitate the production processes of nanostructured (NS) or ultrafine-grained (UFG) materials with unique properties. However, the majority of the efforts were limited on the laboratory-scale investigations not to be able to overcome the demands for industrial scale applications. Researchers have tried to introduce effective industrial methods for processing large and long UFG/NG materials. In this review, all industrial processes especially continuous SPD methods which are more suitable for mass production are categorized and explained. Furthermore, the factors influencing the process efficiency were presented to give a vision to the researchers who want to step in this scientific field. Finally, the industrial processes were compared regarding final microstructure and properties.
