Corrosion Behavior of an AISI/SAE Steel Cut by Electropulsing [PDF]
Materials, 2019 The effect of electropulsing treatment (EPT) on the surface general corrosion behavior of an AISI/SAE 1045 steel under different machining regimes is studied. In the study, the following variables are alternated: high-speed steel (HSS) vs. hard metal (HM), and with and without the assistance of high-density electropulses.

Room temperature texturing of austenite/ferrite steel by electropulsing [PDF]
Scientific Reports, 2017 AbstractThe work reports an experimental observation on crystal rotation in a duplex (austenite + ferrite) steel induced by the electropulsing treatment at ambient temperature, while the temperature rising due to ohmic heating in the treatment was negligible. The results demonstrate that electric current pulses are able to dissolve the initial material’

Electropulsing of pearlitic steels [PDF]
, 2016 Electropulsing is a process characterised by the application of short duration (~100μs) electrical current pulses. The process is claimed to be capable of stimulating microstructure change in a variety of metals at low temperatures and energy levels. In this thesis, electropulsing is applied to examine its potential to produce nanostructured, strong ...

Influence of Electropulsing Treatments on Mechanical Properties of UNS S32750 Duplex Stainless Steel [PDF]
Materials (Basel), 2020 Prestrained at 5% and 15% duplex stainless steel UNS S32750 specimens have been subjected to electropulsing treatments with current density of 100 A/mm2 and 200 A/mm2 and 100 and 500 pulses for each current density value.

Revealing the pulse-induced electroplasticity by decoupling electron wind force [PDF]
Nature Communications, 2022 The origin of the degradation of nanodevices under electrical pulses still remains unknown. Here, Li et al. reveal the mechanism of direct electron-dislocation interaction by decoupling the electron wind force using in situ electropulsing, providing ...

Phase stability in steels under electropulsing [PDF]
, 2015 There are increasing interests to alternate the microstructure and hence the properties of steels that are applied in various environment conditions using a work-efficient and energy-saving manner. The desirable microstructure evolution is often not achievable by means of conventional thermo-mechanical processing and solid-state phase transition.

Embrittlement of 316L stainless steel in electropulsing treatment
Journal of Materials Research and Technology, 2020 Electropulsing treatment is known to induce the so-called electroplastic effect, which is accompanied by an increase in ductility of metals. However, in this study we find that the application of electric current pulse reduces the flow stress and strain ...

Insights into electron wind force by a helical dislocation reconfiguration [PDF]
iScience, 2023 Summary: Many efforts for decades have been made to explore electron wind force, produced by electric current itself under electropulsing treatment. However, the clear evidence of this force is hard to separate from Joule heating. Here we study a helical
