Rate My Professor Yan Ma

Ma's research centers on sustainable metallurgy and metals, with key areas including hydrogen-based direct reduction of metal oxides for producing primary metals and manufacturing metal foams, as well as scrap-based steel design and processing to facilitate CO₂ emission reductions in the metal industry. He has published influential works such as 'Circular steel for fast decarbonization: thermodynamics, kinetics, microstructure behind upcycling scrap into high-performance sheet steel' (Annual Review of Materials Research, 2024), 'Hydrogen-based direct reduction of combusted iron powder: Deep pre-oxidation, reduction kinetics and microstructural analysis' (Acta Materialia, 2024), 'Reducing iron oxide with ammonia: A sustainable path to green steel' (Advanced Science, 2023), 'Hierarchical nature of hydrogen-based direct reduction of iron oxides' (Scripta Materialia, 2022), and 'Phase boundary segregation-induced strengthening and discontinuous yielding in ultrafine-grained duplex medium-Mn steels' (Acta Materialia, 2020). His contributions have been recognized with the Walter Benjamin Award from the German Research Foundation (2021), DGM Prize for Young Talent (2022), Stanford's top 2% most highly cited scientists (2023, 2024, 2025), IJMMM Outstanding Paper Award (2024), and appointment as Outstanding Youth Editorial Board Member of the International Journal of Minerals, Metallurgy and Materials (2024). Ma's research significantly impacts green steel production and sustainable metal processing.
