Effect of current pulses on the drawing stress and properties of Cr17Ni6Mn3 and 4J42 alloys in the cold-drawing process

Effect of pulsed current on the deformation behavior of AZ31B magnesium alloy

“…Conrad [16,17] found that current also affected the phase transition, and suggested that the electroplasticity was caused by the influence of electricity on thermal activation but not the electron wind. Tang et al [18][19][20][21][22][23][24] reported many electrically-assisted technologies including forming and hot treating, which were more excellent than traditional processing. Moreover, Tang et al suggested that the improvement by electricity was derived from the electron wind and the decreased solution temperature of the second phase.…”

Electric current as a steel wire manufacturing tool

“…less for smaller diameters reduction passes 1.3-1.2 mm ∼30% [38]. This, however, does not appear to be a general trend for smaller diameter reductions but material specific.…”

“…Unless otherwise stated, the original condition of drawn samples is an annealed state (authors have not provided specific annealing conditions). A current density of A/mm 2 applied to a precision steel with 42 wt-% Ni, drawn from 1.6 to 1.2 mm in four passes at 6 m/min [38] reduced the drawing force required for the second pass (1.5–1.4 mm) by 47% (577 to 307 N) compared to when drawn without current. The reduction in required drawing force due to applied current was less for smaller diameters reduction passes 1.3–1.2 mm % [38].…”

Behavior and Quality Evaluation of Electroplastic Self-Piercing Riveting of Aluminum Alloy and Advanced High Strength Steel

“…This phenomenon is called as electroplasticity. Even though the mechanism of electroplasticity is controversial so far, the electroplasticity has been studied and applied in various material forming fields to improve the formability of the metals, such as cold-drawing [23][24][25] and rolling [26][27][28] in the past ten years, and the results showed that the electric current could significantly improve the formability of the materials.…”
