摘要：

The unique impact of two types of ferrite, intercritical ferrite and delta-ferrite on austenite stability and deformation behavior of hot-rolled Fe-11Mn-4Al-0.2C transformation-induced plasticity (TRIP) steel were studied. Each of the two ferrites exhibited their respective role in enhancing the stability of austenite, contributing to superior ductility. An optimized quenching at 800 degrees C and tempering at 200 degrees C adopted on the as-hot-rolled steel led to a ferrite-austenite mixed microstructure that was characterized by excellent combination of tensile strength of 1082 MPa and elongation of 35%, and a three-stage work hardening behavior.
