Overview over DTU Wind Energy, the Materials Science Section and Characterization in 3D by synchrotron X-rays
主讲人 : Prof. Dorte Juul Jensen (Technical Univertsiy of Denmark, Denark)
This presentation will first provide an overview over the Section for Materials Science and Advanced Characterization, and the Department of Wind Energy at the Technical University of Denmark. The development of a so-called 3D X-ray Diffraction (3DXRD) technique is then described from idea to implementation. The use of this characterization technique has enabled detailed analyses of materials microstructures in 3D with micron or even sub-micron spatial resolution and to follow the microstructural evolution over time during for example mechanical loading or annealing. This has led to results challenging today’s understanding of key phenomena. Examples of key experiments are given. These experiments would not have been possible without the 3DXRD technique. Limitations of 3DXRD are discussed. On-going technique development and a complementary x-ray method are presented. Finally, challenges and suggestions for the future success of 3D/4D materials science are discussed.
Prof. Jensen is the Professor in the Materials Science and Advanced Characterization Section, Department of Wind Energy, Technical University of Denmark. She received her Ph.D. degree from the Technical University of Denmark and Risø National Laboratory in 1980. Then she worked in Risø National Laboratory and got promoted to Professor in 2012. She currently serves as the head of Section “Materials Science and Advanced Characterization”, Department of Wind Energy, DTU.
Prof. Jensen has published in total 358 papers, including 140 papers in international journals, 57 keynote/invited papers in international conference proceedings, 143 contributed papers in international conference proceedings, 2 chapters in the Encyclopaedia of Materials and 5 chapters in books. Her research interests involve:
(1) Development of advanced characterization techniques
(2) Microstructure and crystallographic texture development during recrystallization
(3) Microstructure and crystallographic texture development during plastic deformation
Prof. Jensen is a member of the Royal Danish Academy of Sciences and Letters, and chairman of the national bibliometric group on materials and nano-technology and science. She has received the Jakob Wallenberg Foundation award, the Danish Knighthood, and the Cook/Ablett Award by the Institute of Materials, Minerals and Mining. She serves on the advisory board for Int. Journal of Materials Research and the editorial board for Materials Transactions.
