Gränges Powder Metallurgy Gmbh, Germany

Benjamin Delignon

Biography

During 10 years in the Additive Manufacturing world, I had the chance to work in France and in Sweden in various industries from Aerospace to Semiconductor, and multiple roles from M&P Qualification, Manufacturing Engineering or Strategy Definition. I recently came back to Material Science and joined Gränges Powder Metallurgy, one of the (too) few companies atomising Aluminium powders in Europe. I am currently the R&D manager.

41 Aluminium Scandium alloys development for hydrogen applications

With an expected annual growth of +4,2% until 2034, the hydrogen market is increasing and the transformation of the existing gas network in Europe is required in the years to come, resulting in the modification of many elements such as On-Tank-Valves (OTV).

In this context, Gränges Powder Metallurgy worked on several Aluminium-Scandium alloys in the last year, using cost-efficient Scandium sourced in Canada, and participated in the development of an OTV to illustrate the potential of Al-Zr-Sc alloys in the AluScal project funded by the German government and in collaboration with multiple actors such as the DLR, Rosswag, or Rio Tinto.

In this project, various Al alloy series were selected and modified with the addition of different contents of up to 0.3 wt% Sc and Zr. After gas atomisation, multiple parts and samples were produced with L-PBF technology and the characteristics of the materials were assessed through different hardnening cycles at various temperatures followed by hardness measurements, tensile tests and corrosion tests.

By characterizing the materials, transferring them to simulation models and developing design guidelines, the foundations are laid for technology transfer to other applications of these materials.
