“…The influence of the athermal effect on these factors was too small to induce recrystallization behaviour alone [ 69 ]. By comparing the true stress-true strain curves of AZ31B alloy under uniaxial tensile tests, the athermal effect under electropulses was confirmed [ 133 , 134 , 135 ].…”

The technology of high-density electropulsing has been applied to increase the performance of metallic materials since the 1990s and has shown significant advantages over traditional heat treatment in many aspects. However, the microstructure changes in electropulsing treatment (EPT) metals and alloys have not been fully explored, and the effects vary significantly on different material. When high-density electrical pulses are applied to metals and alloys, the input of electric energy and thermal energy generally leads to structural rearrangements, such as dynamic recrystallization, dislocation movements and grain refinement. The enhanced mechanical properties of the metals and alloys after high-density electropulsing treatment are reflected by the significant improvement of elongation. As a result, this technology holds great promise in improving the deformation limit and repairing cracks and defects in the plastic processing of metals. This review summarizes the effect of high-density electropulsing treatment on microstructural properties and, thus, the enhancement in mechanical strength, hardness and corrosion performance of metallic materials. It is noteworthy that the change of some properties can be related to the structure state before EPT (quenched, annealed, deformed or others). The mechanisms for the microstructural evolution, grain refinement and formation of oriented microstructures of different metals and alloys are presented. Future research trends of high-density electrical pulse technology for specific metals and alloys are highlighted.

“…Among the researchers working on this subject, Xie et al applied the V-bending process to AZ31B magnesium alloy sheet and investigated the in uence of direct-current pulses on springback. They determined that when grain size and the number of twinning crystals decreased, springback decreased as well [2]. Park et al combined martensitic steel sheet with polymer material as a laminate and produced a new material with high strength (500 MPa).…”

Ultra-high-strength Martensitic 1400 steel is preferred in the automotive industry because of its high strength as well as its light weight. In this study, Martensitic 1400 steel was subjected to the V-bending process. As a result of 48 different tests, the amount of springback resulting from the V-bending process was determined. A finite element (FE) model was then created based on these experimental data. After it was determined that the experimental results concurred with the FE model, without performing new experiments, further analyses were carried out at different temperatures. Using the results of a total of 96 FE analyses, variance analysis was performed and the effects of the operation parameters on springback were determined. As a result of the study, it was concluded that the most effective parameter on springback in the V-bending process was the die angle and that holding time had no significant effect. It was observed that the springback increased in parallel with the punch radius and die angle and that increases in temperature reduced the springback.

“…Sánchez Egea et al (2015) used ECP to assist turning process and found it to be a feasible technique to improve the material machinability. Xie et al (2015) studied the effect of direct-current pulses on bending property of AZ31B magnesium alloy sheet, and found that current pulse could reduce its springback. Furthermore, there are many studies on the mechanisms of effects of ECP on the materials mechanical properties, since Troistkii and Likhtman (1963) first reported the phenomenon that the electrons effected the deformation of zinc single crystals in the brittle state in 1963, which was called "electroplasticity" by Troitskii and Maistrenko (1974).…”
