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