Abstract
A 13%Mn hot-rolled metastable austenitic steel with tensile strength of 1200 MPa and total elongation of 43% was developed. Strain induced phase transformation and phase-specific lattice strain evolution during tensile deformation is unraveled by in-situ neutron diffraction. The steel exhibited austenite → ε-martensite → α-martensite two-stage-transformation during in-situ tension accompanied with serrated deformation behavior, which is attributed to the discontinuous martensitic transformation evidenced by in-situ neutron diffraction.
