Eric Aime Jägle
Specially Appointed Associate Professor
Additive ManufacturingMicrostructure Physics and Alloy Design
Dr. Jägle studied materials science at the University of Stuttgart, Germany, receiving a Dipl.-Ing. degree in 2006.
In 2006/2007 he spent on year at the University of Cambridge, UK. In the M.Phil. course in Materials Modelling, he worked with H.K.D.H. Bhadeshia on simulating the origin of banding in hot-rolled steel.
Afterwards, he returned to Stuttgart for his Ph.D. at the Max-Planck-Institut 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.
After receiving his Ph.D. in 2011, 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. D. 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. The group focuses on various aspects of alloys used in AM such as particle reinforcement, in-process strengthening reactions, hot cracking behaviour, residual stress and in-process metal-gas reactions. The investigated materials include steels, Ni- and Al- based alloys and composites.
Expectations for WRHI
My main motivation to join WRHI is to experience the international collaboration with researchers at a world-leading research university. Seeing how science is done around the world is a great inspiration for my work and fosters personal development.
Establishment of research group “Alloys for Additive Manufacturing” in Max-Planck-Institut für Eisenforschung GmbH with financial supports by third-party funding.
Effect of Nitrogen as process atmosphere in the Laser Additive Manufacturing of Stainless Steel
Project summary: We build stainless steel specimens by Selective Laser Melting under different process atmospheres, Ar and N2. We investigate how much nitrogen enters the material, depending on the process parameters such as laser power and scan speed, and what effect it has on the microstructure, the mechanical properties and the corrosion resistance of the steel.
