Fig. 6. Strain-induced martensitic transformation of metastable austenite and work hardening behavior in ART and CBE steels.

Fig. 6

(A) Strain hardening behaviors of ART and CBE steels. (B) Kinetics of strain-induced martensitic transformation in ART and CBE steels measured by in situ magnetic induction, along with the microstructure as observed by EBSD near the fracture site, where austenite is marked in red in the EBSD maps. The step-like transformation is due to PLC bands passing through the measured volume. The transient increase and decrease in the transformed austenite fraction at the beginning of each step are artifacts caused by the PLC bands entering and leaving the finite magnetic probing area.
