Continuous Severe Plastic Deformation of Low‐Carbon Steel: Physical–Mechanical Properties and Multiscale Structure Analysis

Abstract

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.

Non-Equimolar Cantor High Entropy Alloy Fabrication Using Metal Powder Cored Wire Arc Additive Manufacturing

“…Here, it should be mentioned that multiple drawing steps were performed to avoid diameter reductions of over 23 % in a single draw [27]. Hence, the MPCW wire drawing route was performed as follows: diameter = 3.8 to 3.4, 3.0,2.75 and finally to 2.4 mm (with associated partial reductions of 20, 22, 16 and 23%, respectively).…”

Processing, microstructure adjustments, and mechanical properties of dual phase steels: A review

“…Severe plastic deformation is defined as a group of forming techniques, which involve the application of very large plastic strains to a workpiece under high hydrostatic pressure. In recent years, several researches have been conducted to fabricate and characterise FG, UFG, and nanostructured materials by using SPD techniques [83-86]. These techniques are usually based on a high level of hydrostatic stress without changing the cross section of the sample, which leads to the formation of UFG and nanostructured microstructures with high angle grain boundaries [87-90].…”

Optimal Constrained Groove Pressing Process Parameters Applying Modified Taguchi Technique and Multi-Objective Optimization

“…The potentiality of processing using SPD for different the composites' special patterns was noted, and Equal channel angular pressing (ECAP), High-Pressure Torsion (HPT), Multi-axial forging (MAF), and additional SPD methods were examined (Kulagin et al, 2019;Husaain et al, 2017). The SPD methods were used to continuously draw low-carbon steel (Zavdoveev et al, 2021).…”
