Material Science and Manufacturing Research Group
Introduction of the Research Group
The education activity of the research group covers all of the manufacturing processes and systems that the state-of-the-art production of vehicles takes place today. In the bachelor’s and master’s programs in vehicle engineering, our purpose is to acquaint students with the steps and attitude of mind required for technological design, from material knowledge through technological design to system approach. Our specializations in the B.Sc. and M.Sc. program inspire our students to acquire these skill levels with planning and project tasks. Research activities of the group focus on the properties and application of advanced alloy systems (amorphous and nanocrystalline alloys, hydrogen storage systems) and cover the material science implications of modern technological processes (bonding technologies, laser machining, and additive technologies). Our state-of-the-art instruments also allow us to perform process diagnostics and process optimization tasks. We cooperate with representatives of the multinational and SME sectors of industry, both in educational and research and development, from the past to the present.
