Grain Boundary Structure Ordering via Electroshock Treatment Enhances Strength‐Ductility Synergy
Advanced Science, EarlyView.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.
