文摘

Significant strain hardening capability of low density steel due to substructure development Nano-size partitioning of the austenite (~ 530 nm) and ferrite (~ 500 nm) grains Progressive deviation of twin boundaries from Ʃ3-coincidence due to substructure development Substructure refinement possesses a high portion of the measured flow stress
