Effect of Electroplastic-Assisted Grinding on Surface Quality of Ductile Iron

open access: yesLubricants
Ductile iron is a heterogeneous material. The presence of spherical graphite and a hard and brittle structure makes the surface of the workpiece easily form pits and crack defects under harsh grinding conditions, which seriously affects the service life ...

Investigation of Electroplastic Effect on Four Grades of Duplex Stainless Steels. [PDF]

open access: yesMaterials (Basel), 2019
Since the late 1950s, an effect of electrical current in addition to joule heating on the deformation of metals called the Electroplastic Effect (EPE) has been known. It is used nowadays in the so-called Electrically Assisted Forming (EAF) processes, but

Nanocrystalline Nd–Fe–B Anisotropic Magnets by Flash Spark Plasma Sintering

open access: yesAdvanced Engineering Materials, Volume 25, Issue 18, September 2023., 2023
Flash spark plasma sintering (Flash SPS) is an attractive method to obtain anisotropic Nd–Fe–B nanocrystalline magnets. However, processing control is necessary to promote an optimized microstructure and magnetic performance. The effect of Flash SPS processing variables and its impact on the functional properties are investigated, showing the potential

Sintering behavior of 8YSZ‐Ni cermet: Comparison between conventional, FST/SPS, and flash sintering

open access: yesInternational Journal of Applied Ceramic Technology, Volume 20, Issue 4, Page 2271-2280, July/August 2023., 2023
Abstract Cermets are ceramic metal composites. The metallic phase in the cermet typically undergoes oxidation during sintering in air. Electric field‐assisted sintering processes such as field‐assisted sintering technology/spark plasma sintering (FAST/SPS) and flash involves very high heating rates, short processing time and low processing temperature.

Atom Rearrangement by Cyclic Electron “Shaking”

open access: yesAdvanced Engineering Materials, Volume 25, Issue 12, June 2023., 2023
This study reports a new atom rearrangement technique based on the cyclic electron flow that induces the “shaking” of atoms. The efficient technique can produce a unique arrangement of atoms that cannot be attained using the conventional heat treatment.
