The 2nd Conference of the German Association for Materials Research and Testing (DVM) on additive manufacturing took place in Berlin in November 2017. Thereby, the DVM Junior Prize was awarded. Tobias Thiede from the Micro Non-Destructive Testing Division impressed the jury with his presentation about the results of his work at the BER II neutron reactor.
Additive manufacturing processes are regarded as trend-setting and have long since established themselves for series production, for example in the vehicle industry. Metallic components produced by additive manufacturing sometimes differ greatly from conventional cast or wrought pieces. This is especially true for their microstructure and thus their material properties. There is still a lot of work to be done in the field of characterisation of additively manufactured components. "We want to take on a leadership role. This award brings us a little closer to our goal", explains Tobias Thiede.
Tobias Thiede’s research deals with residual stress analysis in additively manufactured specimens. He uses neutron diffraction, a non-destructive testing method, to investigate technical components for residual stresses. Stresses can easily lead to damage to components with devastating effects. Mr Thiede has also managed to correlate residual stress fields with the chosen scanning strategy during additive manufacturing.
"I am particularly proud of this award because the decision has no political background. It recognises excellent work performed by our young scientists in additive manufacturing", assessed Prof. Dr. Giovanni Bruno, Head of the Micro Non-Destructive Testing Division.
About the DVM
The German Association for Materials Research and Testing has since 1896promoted knowledge transfer in the fields of structural integrity, materials research and material and component testing . Experts from science, research, industry and service companies meet in twelve working groups in a multidisciplinary network and at various events across industries to discuss the latest research results and identify future research goals.
The DVM Junior Prize, newly created in 2011, is an award for young scientists and is granted for an outstanding presentation at a DVM conference. The award recognises this outstanding work and motivates further committed research in the future.
