Outstanding issues in electropulsing processing
, 2015 The processing of materials using electrical pulses utilises effects other than resistive heating to stimulate changes in their microstructure and hence the properties. The direct effect of electropulsing has not, however, been fully understood.

Rapid precipitation of L12 phase in Al0.5CoCrFeNi high-entropy alloy under electropulsing
Materials Research LettersA new strategy for the rapid precipitation (1.8 s) of L12 nanoprecipitates in Al0.5CoCrFeNi high-entropy alloys by electropulsing treatment (EPT) has recently been discovered. The coherent L12 phase was introduced under high temperatures by EPT, and this

Microstructural modification of additively manufactured metals by electropulsing
Additive Manufacturing, 2020 Abstract Additive manufacturing (AM) promises rapid development cycles and fabrication of ready-to-use, geometrically-complex parts. The metallic parts produced by AM often contain highly non-equilibrium microstructures, e.g. chemical microsegregation and residual dislocation networks.

Morphology and distribution control of MnS inclusions in molten steel by electropulsing
, 2014 The morphology, size and distribution evolutions of MnS inclusions in molten steel were investigated by electropulsing. The results show that angular MnS inclusions distributed randomly in the untreated as solidified steel, in contrast to chain-like ...

Plasticity enhancement of Zr-based bulk metallic glasses by direct current electropulsing
, 2014 Direct current electropulsing was used to improve the plasticity of (Zr53Cu30Ni9Al8)(99.5)Si-0.5 bulk metallic glasses. After the electropulsing treatment, the specimen showed reductions in both the glass transition and the crystallization temperatures ...

Dynamic electropulsing induced phase transformations in a furnace cooled Zn-Al based alloy (ZA22)
, 2010 Multi-phase identification and phase transformations in a dynamic electropulsing treated Zn-Al based alloy (ZA22) were studied by using backscattered scanning electron microscopy (BSEM) and electron back-scattered diffraction techniques (EBSD).
