Abstract: The thermal deformation behavior and microstructure evolution of medium Mn steel (0.15C–7Mn) are investigated by the two‐hit compression tests. The results reveal that different static softening dynamics are the functions of deformation temperature, interval time,…

Abstract: Abstract The austenite (γ) reversed transformation of medium-Mn steel during intercritical annealing (IA) process was investigated based on different initial martensite (α') microstructure. The results reveal that the volume fraction of γ phase gradually increases…

Abstract: Abstract Austenite reversion treatment (ART) is usually used to obtain retained austenite (RA) in medium Mn steel (MMS). In this contribution, we proposed a flash-annealing strategy to produce MMS, which allows us to efficiently obtain…

Abstract: ABSTRACT The present work quantifies the contribution of constituting phases to the strain hardening in a medium-Mn steel during Lüders deformation. The strain hardening of the ferrite matrix (∼ 46.1 MPa) is much lower than that…

Abstract: A novel processing route is proposed to create a heterogeneous, multiphase structure in a medium Mn steel by incorporating partial quenching above the ambient, warm deformation, and partial recrystallization at high partitioning temperatures. The processing…
