“…The paper [ 28 ] indicates a decrease in the limiting thickness of the titanium sheet during rolling with current compared to cold rolling, which also depends on the deformation rate, i.e., deformability decreases with increasing speed when other parameters remain unchanged. It was shown in [ 71 ] that the difference in elongation can reach 3–5% during tension with a current of low densities (5–10 A/mm 2 ) compared to tension without current in AA1050 aluminum alloy. In addition, a number of researchers are studying the increase in deformability with current using nonstandard test schemes, for example, shear deformation of the Ti64 alloy [ 72 ].…”

A review of studies on the electroplastic effect on the deformation process in various conductive materials and alloys for the last decade has been carried out. Aspects, such as the mode and regimes of electric current, the practical methods of its introduction into materials with different deformation schemes, features of deformation behavior accompanied by a pulsed current of different materials, structural changes caused by the combined action of deformation and current, the influence of structural features on the electroplastic effect, changes in the physical, mechanical, and technological properties of materials subjected to plastic deformation under current, possible mechanisms and methods of physical and computer modeling of the electroplastic effect, and potential and practical applications of the electroplastic effect are considered. The growing research interest in the manifestation of the electroplastic effect in such new modern materials as shape-memory alloys and ultrafine-grained and nanostructured alloys is shown. Various methods of modeling the mechanisms of electroplasticity, especially at the microlevel, are becoming the most realistic approach for the prediction of the deformation behavior and physical and mechanical properties of various materials. Original examples of the practical application of electropulse methods in the processes of drawing, microstamping, and others are given.

“…Many advantages have also been shown during the application of electricity to other plastic deformation processes, such as rolling [11] or wire drawing [12]. In the case of studies on the influence of electricity on the material's behavior in different states of hardening, Simonetto et al [13] demonstrated that the application of direct current has a greater impact on the 1050 aluminium alloy in the H24 state than in the annealed state. Other studies have also proved various effects of the current on the material's behavior in different states of hardening in the case of the 5xxx [14], 6xxx [15], and 7xxx aluminium alloy [16].…”

This study presents the effect of high current pulses on the structural and mechanical behavior of the 6016 aluminium alloy in three different states of hardening: naturally aged, super saturated, and annealed. The 6016 aluminium alloy was used for the first time in terms of electrically-assisted forming. The influence of the application of different current parameters on the material behavior was conducted. The study of electrically-assisted tensile tests showed that the application of current pulses results in a distinct response of the material, depending on the hardening state. Although in a hardened state, the mechanical properties and plasticity are deteriorated, in the solution treated state, they are improved. For the changes of the material properties is responsible the interaction of the flowing current with the precipitates and the aging process. The new parameters were proposed to describe the distinctions in the material properties between the different states of hardening of the aluminium alloy during the electrically-assisted tension. The material examination was conducted using light and scanning electron microscopy, using also electron backscattered diffraction methods. The application of, for example, the grain orientation spread parameter demonstrated the presence of recrystallized grains, in electrically-assisted specimens.

“…Electrically-Assisted Forming (EAF) is proposed as an alternative method to the warm and hot forming methods. It is commonly known that the application of current pulses during plastic forming of metals can significantly increase their formability, reduce flow stress, and avoid or reduce some of the above-mentioned drawbacks [5][6][7]. Jeong et al [8] showed that the application of current pulses during tension can increase the material elongation by over 200% in the case of the 5052-H32 aluminium alloy (AA) [9] and the as-extruded AZ91 magnesium alloy.…”

Abstract. The effect of current pulse application on the mechanical behaviour and plasticity of the 5754 aluminium alloy was studied. Tensile and deep drawing tests were conducted. The 5754 aluminium alloy in two different states of hardening was used: H111 and H22. The results show that the application of current pulses can significantly increase the plasticity of the examined alloys in the case of the tensile test. The dynamic recovery process is the main process responsible for the increase in plasticity of the material. However, in the case of the deep drawing process, it was observed that the increase in the material formability is low, and further studies are needed.
