"Simulation of the mixed microstructure in new Q&P high strength steels"
The new Q&P (Quenching & Partitioning) process opens up the way to develop steel microstructures based on the exceptionally advantageous combination of austenitic and martensitic phases at the industrial scale. The industrial applicability of the Q&P process will be improved in terms of compositions, processing, and microstructure control to develop a reproducible production process for the new Q&P steels. The current advances in computational techniques will accelerate the development and optimization of the emerging Q&P steels.
Incorporating computational thermodynamics and diffusion kinetics, the project aims at developing a new quantitative Gingzburg-Landau model to simulate, understand and optimize the mixed microstructure, consisting of retained austenite and martensite, for new Q&P Q&P steels with improved strength, ductility and strain hardening for application in the automotive sector.
The research activities of this project will lead to a doctoral thesis within the doctorate program of the Polytechnic University of Madrid under the scientific supervision of Dr. Yuwen Cui and Prof. Javier LLorca.
