Materials Design for Quench and Partition Steels (Room 311)

Tracks: Product Metallurgy of AHSS, Steelmaking Fundamentals

Quench and Partitioning (Q&P) steel is a novel concept that promises to take the third generation of advanced high-strength steels (AHSS) to better combinations of strength and ductility while reducing the overall manufacturing costs. The concept of materials design, along with advanced experimental characterization techniques, is used to determine optimized Q&P processing routes and design better steel compositions. This work showcases the applicability of a thermodynamics-based genomic design approach to the manufacturing of AHSS. The microstructure consists largely of martensite laths with thin films of retained austenite which provide the excellent mechanical properties via the TRIP effect. Para-equilibrium simulations are compared and calibrated to highly accurate experimental measurements using 3D atom probe and electron microscopy.
