Adding transformation-induced plasticity (TRIP) effect to martensitic steel, is a powerful strategy to produce materials for future lightweight vehicles, which combines great ductility with high strength. However, the additional strain hardening capacity gained by the martensitic transformation of metastable austenite is limited due to the consumption of the austenite with deformation. Here in this work, we present a novel approach to utilize post-deformation resetting treatments to repeatedly restore the original austenite-martensite structure, thereby increasing the cumulative ductility of the material. In addition, phase transformation mechanisms during deformation and resetting processes are unraveled by mapping heterogeneous evolution of plastic strain, interface characteristics, crystallographic defects, and elemental segregation. This approach thus enables continuous recharging of the mechanical properties through the proposed deformation-resetting treatments. The guidelines that are developed through a deeper understanding of the mechanisms involved, make it also possible for the resetting concept to be applied to various other materials.
