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 ...

Temperature-dependent electroplasticity in the Invar 36 alloy

Journal of Materials Research and Technology
Electroplasticity of the Invar 36 alloy is investigated based on comparisions between warm and electrically-assisted (EA) uniaxial tensions experiments at different temperatures (100–600 °C) and corresponding microstructural characterizations. Under warm

Heat Treatment of AA7075 by Electropulsing and DC Current Application

Journal of Manufacturing and Materials Processing, 2023
Electrical resistivity was used in this test methodology to estimate the relative precipitate density in AA7075. Various electrical test parameters were explored to determine the difference between pulsed and DC-type currents. No difference between these

Excellent Ductility in the Extruded AZ61 Magnesium Alloy Tube Induced by Electropulsing Treatment during Tension

Metals, 2021
In this work, we reported the high ductility of an extruded AZ61 magnesium alloy tube achieved by electropulsing current-assisted tension. The elongation of the alloy reached up to about 45%, which is largely superior to the majority of AZ61 wrought Mg ...

Analysis of the prospects of the application of the electroplastic effect in the processes of processing metals with pressure

Литьë и металлургия, 2020
The mechanical properties of metals change temporarily or permanently under the influence of a high density electric current in the deformation zone. This phenomenon is called electroplasticity, and its use makes it possible to intensify the process of ...

Creep and Superplasticity of Gadolinium‐Doped Ceria Ceramics under AC Electric Current

Advanced Engineering Materials, Volume 25, Issue 18, September 2023., 2023
The application of electric field/current results in enhanced plasticity of ceramics which is inherently brittle. The present work is an investigation of plasticity of gadolinium‐doped ceria (GDC) ceramics under weak and strong electric currents, while subjected to compressive and tensile stresses to induce creep deformation.
