This book offers new insights into the process of adjusting nanostructures in high-strength steels to achieve enhanced mechanical properties. It summarizes the state-of-the-art nanoengineering approaches, such as precipitation engineering, interface engineering, and short-range ordering engineering. The book explores the nanostructure-process-property relationships in various high-strength steels, including TRIP/TWIP/MBIP in high-Mn steels (HMnS), medium-Mn steels (MMnS), bearing steels, tool steels, and more. The author investigates a novel approach to control the phase transformation process during deformation and/or thermal treatment in steels, employing both experimental and theoretical tools.

Prof. Dr.-Ing. habil. Wenwen Song completed her Ph.D. study with "summa cum laude" at Steel Institute (IEHK), RWTH Aachen University in 2014. During 2016-2022, Prof. Song worked as the group leader of Nanostructured Materials at RWTH Aachen. Prof. Song was a guest scientist at the University of Cambridge, UK during 2015-2016, and won Théodore von Kármán Fellowship at the University of Oxford in 2018. During 2017-2019, she served as a scientific leader of Cloud III, "Hydrogen Management", within the Collaborative Research Centre SFB 761 "Steel - Ab initio: Quantum mechanics guided design of new Fe-based materials" at RWTH Aachen. In January 2021, she completed her habilitation on the topic of "Nano-engineering of high strength steels" at RWTH Aachen University and was awarded with the Venia Legendi of "Nanoengineered Materials". Prof. Song was awarded several prizes for innovative research and teaching, e.g. the Steel Innovation Prize 2018 in Berlin, the Junges Kolleg (young academy)prize in 2019 at NRW Academy of Sciences, Düsseldorf, and the "Distinguished RWTH Lecturer" prize 2020 at RWTH Aachen, etc. Prof. Song's research expertise is mainly specialized in developing structural metallic materials using multi-scale correlative materials characterization and simulation techniques. Prof. Song was appointed by the University of Kassel, Germany, since 2023 as the head of the department for "Granularity of Structural Information in Materials Engineering" at the Institute of Materials Engineering. Her research focuses on developing novel metallic materials and processes for various sustainable applications.
