About author:
Dr. Huang is currently an Associate Professor at Depart-ment of Mechanical Engineering, University of Hong Kong. He received his BEng and MSc in Solid Mechanics from Shanghai Jiao Tong University (SJTU) in 2002 and 2004, respectively, and his PhD in Materials Science from Delft University of Technology (TU Delft) in 2008. Dr. Huang was a Research Engineer at ArcelorMittal in Maizieres-les- Metz, France, from 2008 to 2010. In 2010, Dr. Huang joined University of Hong Kong as an Assistant Professor and was promoted to Associate Professor with tenure in 2016. He is an editorial board member of Materials Science and Tech-nology and Metallurgical and Materials Transactions A. Dr. Huang received twice the Outstanding Reviewer Award from Scripta Materialia. Dr. Huang’s works have been published in top journals of his research field including Science, Acta Materialia, Journal of Mechanics and Physics of Solids and International Journal of Plasticity. His current research inter-ests focus on two areas: (1) fundamentals of microstructure-property relationship and phase transformation of metals and alloys, and (2) development of lightweight high-strength steels for automotive applications. Both experimental and modelling works are involved in his research. Dr. Huang’s research projects include funda-mental projects as well as industry-oriented projects and have been well funded by General Research Fund, Innovation and Technology Fund, National Science Foun-dation of China, and industries from Europe and China (e.g. ArcelorMittal France, General Motors, Ansteel).

Fig. 1. (A) Schematic illustration of the D&P process. WR: warm rolling; CR: cold rolling; RT: room temperature. (B) Electron backscattered diffraction (EBSD) phase image of present steel prior to warm rolling. Yellow: martensite; Aqua: austenite. Black line represents high angle grain boundaries (>15°). (C) Engineering stress-strain curves of two D&P steels with two different tempering durations measured at room temperature and quasi-static strain rate [64]. (D) The synchrotron X-ray diffraction (XRD) profiles of D&P steel at different strains.
Fig. 2. (A) Schematic illustration of the proposed methodology for incorporating the dislocation engineering concept to the Q&P steels. (B) Target tensile properties of the Q&P steels produced by the routes as shown in (A). TS: tensile strength; EL: total elongation.
