We congratulate Felix Großwendt, who successfully completed his doctoral dissertation on May 8, 2026, on the topic “In-situ alloying using novel powder feedstocks for laser powder bed fusion of tool steels.” The dissertation describes research into the processing of mixtures of different raw material powders in laser-based additive manufacturing to produce chemically homogeneous components. This is intended to expand the available range of starting materials without relying on the cost-intensive inert gas atomization of pre-alloyed melts. In addition, the use of grinding chips as secondary powders in additive manufacturing and powder metallurgy was investigated.
