Evolution of microstructures in materials induced by electropulsing

Electroplastic cutting influence on power consumption during drilling process

“…When the current pulses of short duration passed through the specimen, the Joule heating effect occurred in the specimen. Due to very short duration of EPs, the material particles undergo heavy stress impact [18]. Because of the increase of current density, a higher rise in temperature would be produced and hence the maximum stresses will be increased during EPs treatment, as shown in Table 5.…”

Surface modification of an austenitic stainless steel wire by a multi-pulse treatment with a high-power electric current

“…These twins were found to originate mechanically because of high mechanical stresses created by shock waves arising in a cylindrical specimen. Besides, the nano-structures were observed in various materials including aluminum alloys and lowalloyed steels [10] after electric pulse treatment. On the other hand, Xu et al observed recrystallization [11] after applying several electrical pulses.…”

Electropulsing-induced phase transformations in a Zn–Al-based alloy

“…1 As an alternative to the traditional thermal and mechanical processes, EPT has been recognized for its high efficiency, and extensive studies in materials science and engineering have been carried out in such areas as electroplasticity, [2][3][4] electromigation, 5,6 recrystallization, 7-9 phase transformations, [10][11][12][13][14][15] and in the mechanism of interaction between electrons and lattice atoms and dislocation movement. [16][17][18] EPT has also been applied to materials processing, in such areas as cold drawing, recovering cracks and flaws, and refining grain size, as well as in biology and environmental protection and in the medical domain.…”
