Design of metastable austenite (RA) has been one of the most key issues in the development of advanced high strength steels (AHSS) as mechanical properties of AHSS are directly linked to the amount of RA and its stability. In the past decades, several approaches, e.g. isothermal bainitic transformation (IBT), Quenching & Partitioning (Q&P) and austenite reversion transformation (ART) et.al, have been successfully proposed to obtain RA in AHSS. However, up to now, optimization of processing parameters and alloy composition in the above approaches is primarily by “trial and error” experiments or thermodynamic calculations. In this study, we will present a physical model, in which thermodynamics and transformation kinetics are carefully considered, to design RA in AHSS. The effect of processing parameters and alloy composition on the amount of RA and its stability will be discussed.
