Effects of Retained Austenite Stability and Microstructure Refinement on Properties of Advanced High Strength Sheet Steels: Nina Fonstein¹; ¹Retired, ArcelorMittal in East Chicago
     Evolution of AHSS to meet automotive challenges resulted not only in development of new types of steels including so called the 3rd generation (medium Mn steels, carbide free bainitic steels, Q&P steels), but also in significant changes of “traditional” steels as DP, TRIP and Complex Phase steels aiming to increase their combination of strength and ductility. Based on both literature and own experimental data the current review considers various aspects of potential effects of retained austenite stability which is different in different steels. Different parameters of retained austenite stability are compared. The key role of structure refinement in achievement of higher ductility is shown for different types of steels, and analysis of ways to obtain structure refinement is presented.
