Abstract

Quenching and partitioning (Q&P) of steels is a processing strategy that can be used to create microstructures containing retained austenite and martensite, which may provide strength and ductility combinations of interest for 3^rd generation advanced high strength steels (AHSS). The aim of Q&P is to stabilize the austenite by increasing its carbon content via partitioning from martensite. Thus, understanding the kinetics of transition carbide formation is important for the development of Q&P steels, since the formation of transition carbides may consume carbon that could otherwise be used to stabilize austenite. Advanced electron microscopy techniques were used to characterize Q&P microstructures and to determine the presence of transition carbides. Tensile properties were also determined, and dilatometry was used in some instances to perform Q&P heat treatments and determine relevant phase transformation temperatures.
