China News Service, Dongguan, September 15 (Xu Qingqing, Zhang Wei) The Sino-German Engineering Materials Neutron Scattering Forum and Neutron Full Diffraction Profile Fitting Tutorial opened in Dongguan on the 14th. The event brings together experts and scholars in the field of neutron scattering from China, Germany, Hungary and other countries to build a high-level international academic exchange and young talent training platform.
The forum was hosted by the Institute of High Energy Physics of the Chinese Academy of Sciences and the Spallation Neutron Source Science Center, and was funded by the National Natural Science Foundation of China and the German Research Foundation (DFG) Sino-German Mobility Program.
According to reports, neutron scattering, as an important non-destructive characterization method, can analyze the internal microstructure and residual stress of engineering materials, and plays an irreplaceable role in the research and development of advanced materials such as aerospace, rail transportation, energy storage, and superconductivity.
During the forum, Michael Hofmann, head of engineering materials spectrometer at the German MLZ Research Center, elaborated on the unique value of Sino-German cooperation from three levels: technological complementation, experience sharing, and standard co-construction. He said: "Different partners each have exclusive technical expertise, and shared experience can build a larger knowledge system than independent research. This cross-institutional experience sharing model has provided key support for recently completed key scientific research projects." He said that bilateral scientific research cooperation must be a two-way communication process, and both parties need to obtain corresponding benefits from it to form a win-win situation, so as to build a long-term and stable healthy cooperative relationship.
Li Xiaohu, head of the China Spallation Neutron Source Engineering Materials Neutron Diffraction Spectrometer, said: "Sino-German bilateral cooperation has achieved a number of practical results, promoting the full-process debugging of the China Spallation Neutron Source's first engineering materials spectrometer to be recognized at the international level, significantly shortening the debugging cycle, and quickly meeting the international standard recognition requirements for engineering material stress measurement."
Regarding follow-up cooperation, Li Xiaohu revealed that the two parties will promote relevant cooperation on the remaining spectrometers based on the existing cooperation. China and Germany will also jointly apply for a new round of in-depth cooperation at the research institute level.
It is reported that the MLZ Research Center of the Technical University of Munich in Germany is the world's top high-throughput neutron scientific research platform, and the China Spallation Neutron Source (CSNS) is China's first pulsed spallation neutron source. The two parties have long-term in-depth cooperation in residual stress testing, data analysis standardization, experimental equipment iteration, etc., continue to carry out academic exchanges, and cultivate young scientific research teams.
The neutron full diffraction profile fitting tutorial class held at the same time was held from September 15 to 18. The training class was led by Professor Tamás Ungár and Professor Gábor Ribárik, the founders of the CMWP method. The course takes into account both theory and practice, and focuses on core content such as grain size effects and strain anisotropy.
