Modeling the Work Hardening Behavior of High-Manganese Steels

The work hardening of a series of high-manganese steels with various chemical compositions (manganese contents of 18–30 wt.% and carbon contents of 0.06–1.2 wt.%) and deformation products (mechanical twins and/or ε-martensite) was modeled using a physics-based model. The model comprised the contributions of dislocation glide and phase transition (mechanical twinning and/or ε-martensite formation) kinetics to the overall work hardening rate. The …
