Innovative research topics presented at the 4th Graduate Day
Prospective and young graduates of Bachelor's and Master's theses and doctoral projects from Clausthal and Hanover presented their materials-related work at a conference at the Clausthal Center for Materials Technology at the end of the summer semester.
The speakers were all CZM members, i.e. mainly from Clausthal University of Technology, but many participants from various institutes at Leibniz Universität Hannover and the Laser Zentrum Hannover also accepted the invitation. The focus was naturally on materials: from production and testing new manufacturing techniques to metrological property characterization.
The detection and control of intermetallic phase formation when incompatible metallic material pairings come into contact continues to be a topical issue. Either as a desired reaction for the targeted joining of components, such as in steel-aluminum composite casting; or as an undesired effect in the contact between copper electrode and aluminum sheet during resistance spot welding in the automotive industry.
Other presentations dealt with the topic of "Oxygen-free production" in accordance with the Collaborative Research Center 1368 of the same name. On the one hand, the possibilities and mechanisms of oxide reduction on metal surfaces by means of dielectrically impeded plasmas were reported on. On the other hand, presentations were given on the possibilities of coating tools and workpieces under oxygen-free conditions.
All participants presented their topics convincingly, as Dr. Henning Wiche noted in his closing remarks and thanked everyone in advance for the new research ideas gained during the day, which will be quickly tested for their feasibility in experiments. After a snack for further networking, the event came to an end. The next graduate day is planned for 2026.
