Speaker: Eric Jägle Professor of Materials for Additive Manufacturing at the Institute of Materials Science Bundeswehr University, Munich, Germany
Topic: "Some challenges and opportunities in metal additive manufacturing: new alloys, in-situ reactions and metamaterials"
Abstract
n this presentation, I will cover three topics where Additive Manufacturing enables new concepts for the physical metallurgist: First, I will show why new Al alloys tailormade for AM are required and how they are designed and prototyped. Next, I will cover several advantageous in-situ reactions during the process: precipitation and metal-gas interactions. Finally, I will touch one subject where the “complexity advantage” of AM and metallurgy are combined: negative-CTE metamaterials.
Biography
Prof. Jägle studied materials science at the University of Stuttgart, Germany, and at the University of Cambridge, UK, earning a Dipl.-Ing. and an M.Phil. degree (2001-2007). For his Ph.D. (2011), he worked at the Max-PlanckInstitut für Metallforschung (MPI for Metals Research) under the supervision of Prof. E. J. Mittemeijer. His work focused on the mesoscopic simulation of microstructure development during phase transformations, in particular during recrystallization. Afterwards, he moved to the Max-Planck-Institut für Eisenforschung (MPI for Iron Research) in Düsseldorf, Germany. There, he worked as post-doctoral researcher in the department of Prof. Raabe on Atom Probe Tomography analysis of electrical steels, precipitation transformations and mechanical alloying. In 2015 he became leader of a newly formed group in the same department working on alloys for Additive Manufacturing. In 2020, he moved to the Institute of Materials Science of the Bundeswehr University Munich as full professor, continuing his work on alloys used in AM. His research focus includes topics such as particle reinforcement, in-process strengthening reactions, hot cracking behavior, residual stress and in-process metal-gas reactions. The investigated materials include steels, Ni- and Al- based alloys and composites.
