Chair ‘Materials Science and Engineering for Metals’ at FAU

The Chair of Materials Science and Engineering for Metals (WTM) under the lead of Prof. Dr. Körner is a part of the department of Materials Science of the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU). Currently, more than 50 research fellows, professors and international visiting scientists are working at WTM. The research focus at WTM lies on the development of metallic materials and their processing technologies using additive manufacturing. In particular, WTM has more than 15 years’ experience in the realm of selective electron beam melting (SEBM) concerning material and process and machine development. Extensive knowledge has been gained to correlate SEBM process, microstructure and properties of numerous metallic materials. At present, four SEBM systems are available at WTM, and different high performance materials, such as, titanium alloy (Ti-6Al-4V), Ni-based superalloys (In718, CMSX-4 etc.), intermetallic phases (FeAl and TiAl) and copper (pure copper and alloys) are being investigated for the SEBM process.

In the Tubulyze joint project, as a key component for the tubular Polymer-Elektrolyt- Membran (PEM) electrolyzer, porous cylindrical anode composed of Ti-6Al-4V with a wall thickness of ~1 mm, an outer diameter of 5 mm and complex inner structures will be fabricated at WTM using the electron beam based additive manufacturing. In order to have defined porosity, pore size and high geometry accuracy of the Ti-6Al-4V anodes, novel process strategies during SEBM are being under development. Moreover, based on the additive manufacturing technology, the inner structure of the tubular PEM-cell for the water flow can be exactly tailored and optimized.
