Enhanced Electroplasticity through Room-Temperature Dynamic Recrystallization in a Mg-3Al-1Sn-1Zn Alloy. [PDF]
Materials (Basel), 2021 It has been well known that electric pulse can be utilized to enhance the plasticity of metals, which is attributed to the change of dislocation dynamics, e.g., localized planar slip to homogeneous wavy slip. Here, we show another effect of pulse current,

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