Max Planck researchers win TMS Light Metals Subject Award – Aluminum Alloys

November 18, 2019

Dr. Baptiste Gault, Prof. Dierk Raabe and Dr. Huan Zhao from the department “Microstructure Physics and Alloy Design” and their colleagues from the Grenoble Institute of Engineering (France), the Queen’s University (Canada), and Constellium, a producer of aluminium goods, have been honoured with the TMS Light Metals Subject Award – Aluminum Alloys. The prize is awarded by the TMS Minerals, Metals & Materials Society and recognizes excellent papers within a specific subject area, which were published in the preceding year’s volume of the journal Light Metals. The authors won the award for their paper “Understanding the role of Cu and clustering on strain hardening and strain rate sensitivity of Al-Mg-Si-Cu Alloys”.

Dr. Huan Zhao, postdoctoral researcher at the Max-Planck-Institut für Eisenforschung, was responsible for the sample preparation with the plasma focused ion beam (seen in the photo) and the analysis of the samples with atom probe tomography.

The researchers analysed a class of aluminium alloys, which is especially interesting for lightweight design in vehicles, as they are strong and light at the same time. However, car designers are until now discouraged by the material’s lack of formability. The Max Planck scientists and their colleagues analysed the effect of copper on the microstructure and mechanical properties of the alloy class and assume alloy concepts, which enhance the formability and thus pave the way for a usage in lightweight design. Using strong and light alloys means saving material and fuel, thus making the production of vehicles more sustainable.
