Metallurgical Research

Metallic materials and the products made from them carry human civilization since more than 5000 years. With a daily turnover of 3.5 Billion € in the EU alone they are a key driver in economy.
‘Materials’ are a specific type of matter that is finally used for something, be it a product or process. Therefore materials science has generally both a basic and an applied facet. Nowadays, after virtually thousands of years of development, we still use only about 1000 different types of metallic alloys out of a sheer infinite combinatorial space of about 1060 possible combinations when considering only the 50-60 frequently used elements. This means that we only stand at the beginning of metallurgical research.
Currently three developments are revolutionizing materials research. The first one is the availability of models with predictive capability such as provided by density functional theory, advanced quasi-particle and continuum simulation methods as well as big data driven tools related to machine learning. The second one is the availability and concerted use of highest resolving characterization tools such as corrected electron microscopes, atom probe tomography, synchrotron and neutron imaging. The third one is materials synthesis, which stretches nowadays from chemical processes, combinatorial casting to additive manufacturing providing fast and flexible routes for materials fabrication. 
All these techniques enable us to solve some of the most essential challenges in the fields of mobility, energy, infrastructure, medicine and safety

Metallurgy, innovation, materials science and engineering, metallic materials, alloy design About 70% of all innovations in Europe are associated with progress in the fields of materials science and engineering. In the grand challenges that modern societies face, metallic materials occupy key roles.
