Abstract

En 中文

• A multi-physics assisted WEDM-ECM process was proposed for surface strengthening. • A cross-scale framework was established to predict process-microstructure-property relations. • Multi-physics induced phase transformation pathways and microstructural reorganization enhance microstructural stability. • Enhanced properties stem from heterostructure formation, dislocation control, and suppression of irreversible retained austenite.
