Sustainability Talks - 16.01.2024

Das Institut INATECH und das Leistungszentrum Nachhaltigkeit Freiburg laden ein zum Vortrag von Prof. Dr. Dierk Raabe mit dem Titel “Some Materials Science Aspects Behind Sustainable Steel” am Dienstag, den 16. Januar 2024 um 17:15 Uhr.

Der Vortrag findet in Präsenz im Raum SR 02-016/18 Faculty of Engineering, Gebäude 101 Georges-Köhler-Allee 101, 79110 Freiburg statt. Im Anschluss wird es einen kleinen Umtrunk geben. 

The lecture presents progress in understanding key mechanisms of hydrogen-based solid-state and plasma smelting reduction of iron ores. The kinetics of the reactions depend on mass transport kinetics, nucleation during the multiple phase transformations, the oxide’s chemistry and microstructure, and on micromechanics, damage and fracture associated with the phase transformation and mass transport phenomena occurring during reduction. Understanding these effects is key to make hydrogen-based reduction of iron ores commercially viable, enabling massive CO2 reductions in this sector. Questions addressed include (a) How to make green steel by direct reduction and by plasma reduction? (b) Which are the bottleneck research questions in green steel making? (c) Which oxide and reductant feedstock types can be used in green steel making?

Prof. Dr. Dierk Raabe studied music, metallurgy and metal physics. After his doctorate 1992 and habilitation 1997 at RWTH Aachen he received a Heisenberg fellowship and worked at Carnegie Mellon University. He joined Max Planck Society as a director in 1999. His main interest today is to make industrial production more sustainable, focusing on basic research where the leverage for CO2 elimination is particularly large. His specific interests are in sustainable metals (specifically green steel), physical metallurgy of metallic alloys, steels, hydrogen, aluminium alloys, atom probe tomography, machine learning, green manufacturing and metal combustion. He received the Gottfried Wilhelm Leibniz Award and two ERC Advanced Grants. He is professor at RWTH Aachen and at KU Leuven.
