Evaluation of microstructure variation of TC11 alloy after electroshocking treatment
Lechun Xie,Chang Liu,Yanli Song,Haojie Guo,Wang Zhongqi,Lin Hua,Liqiang Wang,Lai-Chang Zhang +7 more
TL;DR: In this article, the authors investigated the effect of electroshocking treatment on the microstructure and mechanical properties of titanium alloys and found that the energy introduced by EST resulted in changes to the direction and intensity of texture within the micro-structure with the texture intensity of the α phase increasing from 4.94 to 8.52 and that of β both increased from 3.35 to 9.88 after 0.04 s EST.

Effect of interfacial reaction behavior on the submerged entry nozzle by the electric current pulse
TL;DR: In this article, the formation process of clogging and the erosion mode of the submerged entry nozzle were studied under an electric field, and the results showed that the electric current pulse applied on the entry nozzle can effectively restrain erosion and maintain the integrity of the sub-entrance.

Simultaneously Enhanced Strength and Ductility of Al-Mg-Si Alloys during Aging Process Induced by Electro-Pulsing Treatment
TL;DR: Systematic electron microscopy characterization and finite element simulation reveal that EPT promotes the formation of clusters Mg2(Si,Cu)3 and sub-grain boundaries, which lead to higher mobile dislocation density, appearance of new crystal orientations, and prevention of crack propagation.

Electromigration in thin aluminum films on titanium nitride
TL;DR: In this paper, the aluminum electromigration drift velocity was measured at the temperature range 250-400°C and an activation energy of 0.65 eV was found for the drift velocity, which was explained by opposing chemical gradients created by the atom pile-up and depletion at the stripe ends.

Overview no. 49: On the mechanisms for the electroplastic effect in metals
TL;DR: In this paper, the effects of high density dc current pulses (10 3 A/mm 2 for 60 μs) on the flow stress of a number of polycrystalline metals (Al, Cu, Ni, Fe, Nb, W and Ti) tested in uniaxial tension at 300 K were investigated with the objective of determining the mechanisms responsible for concurrent load drops.

On the thermodynamics and kinetics of electropulsing induced dissolution of β-Mg17Al12 phase in an aged Mg–9Al–1Zn alloy
TL;DR: In this article, a model for the temperature field of a strip under EPT was established based on the contributions of the coupling of the thermal and athermal effects with the free energy and the direct electron-atom interactions, the thermodynamics and kinetics of the electropulsing induced dissolution of β -Mg 17 Al 12 are discussed.

Evolution of microstructures in materials induced by electropulsing
TL;DR: Nanostructures were formed in several conventional materials under single electropulsing, that is nanophases of alpha-Cu(Zn) and beta'-(CuZn), and orientated nanosized TiC in a TiC/NiCr cermet, which can be attributed to the competition of many factors induced by electropulse.
