Grain Boundary Structure Ordering via Electroshock Treatment Enhances Strength-Ductility Synergy. [PDF]

open access: yesAdv Sci (Weinh)
Electroshock treatment triggers atomic rearrangement, transforming disordered grain boundaries into ordered states without inducing recrystallization. This grain boundary ordering effectively relieves strain concentration and strengthens boundaries, enabling a simultaneous improvement in both strength and ductility.

Dynamical simulation of EBSD master pattern of nickel

open access: yes, 2023
Dynamical simulation of an electron backscatter diffraction (EBSD) master pattern of nickel (Fm\(\bar{3}\)m, a = 3.5236 Å). The master pattern was simulated with EMsoft v4.3.
