Dissertation on novel joining process awarded international researcher prize

Dr. Anna Regensburg, former research associate at the Production Technology Group at TU Ilmenau, has been awarded the Henry Granjon Prize in Tokyo. The prestigious award for young scientists is presented annually by the International Institute of Welding (IIW) in four categories in the field of joining technology.

The aluminum and copfer joints studied by Dr. Anna Regensburg in her dissertation are of particular importance for applications in the field of electromobility

In her dissertation "Hybrid Friction Eutectic Bonding (HFEB) - materially bonded joining of aluminum and copper using the eutectic reaction", Dr. Anna Regensburg, who worked as a research assistant and head of Press Welding in the Production Technology Group at TU Ilmenau before moving to industry, dealt with the production of so-called materially bonded joints, which are mainly used to reduce weight and costs in automotive construction.

With the joining process considered by Dr. Anna Regensburg, high-quality joints can be produced quickly and cost-effectively from similar and dissimilar materials. The special feature, however, is that the eutectic reaction between two different materials is used as the basis for joint formation. Compared with conventional fusion welding processes, the materials to be joined can thus be joined below the respective melting temperatures. This is of particular relevance when joining aluminum and copper, as it allows undesirable intermetallic phases to be reduced. From an industrial point of view, this is of enormous importance in the manufacture of battery contacts as well as on-board power supply components in the field of electromobility, as this can result in significant reductions in mechanical and electrical properties.

Dr. Regensburg's scientific work was conducted at the Production Technology Group under the supervision of Prof. Jean Pierre Bergmann. "The award of this international prize highlights the importance and scope of Anna Regensburg's and TU Ilmenau's work in this field of research," said Prof. Bergmann. "By developing the process from the fundamentals to application-relevant issues, Dr. Regensburg is making a significant contribution to the industrial use of the process."

The Production Technology Group at TU Ilmenau has been active in research and teaching for more than 60 years. During this time, the scientists of the research group have actively shaped the change in production. Today, the focus of the group is on pressure welding, laser material processing, arc technology, additive manufacturing and machining. The research focus is on materials and process engineering studies of metals, mixed metallic compounds, hybrid composites and plastics.
