The Sino-German Workshop of “Building the bridge between physics and material science in amorphous metals”
Oct. 13-17, 2010, Beijing
Organizers:
Chinese side: Prof. Dr. W. H. Wang, P. Wen (Institute of Physics, Chinese Academy of Sciences);
German side: Prof. Dr. K. Samwar, B. Zhang (I. Physikalisches Institut Universitaet Goettingen);
Supported by: Sino-German Center for Research Promotion;
Metallic glasses are of current interest and significance in condensed matter physics, materials science and engineering because of their unique structural features and outstanding mechanical, physical and chemical properties which provide model systems for studying some long-standing fundamental issues and have potential engineering and functional applications. Bulk metallic glass (BMG) forming systems are multicomponent alloys that vitrify with remarkable ease during conventional solidification. The bulky size of the new families BMGs provide plentiful precise knowledge of fundamental parameters of elastic moduli, which offer a benchmark reference point for application and understanding the glasses. In last 20 years, significant amounts of various BMG systems and data on mechanical and physical properties as well as the information on the microstructural characteristics have been collected. However, little work has been done on the physics of the metallic glasses, and attention mainly is paid on the material science aspect of the materials, and the nature and formation of metallic glass remains one of the least understood subjects in condensed matter physics and material science today, because of the highly complex and many-body nature of the problem.
The workshop of "Building the bridge between physics and material science in amorphous metals" was organized to overcome this difficulty and to start establishing the common language and bridge the research between physics and material science in metallic glass field.
The workshop, hold in Beijing from 13th - 16th, Oct. 2010, is co-organized by Prof. K. Samwer and Dr. B. Zhang of University Goettingen, and Prof. W.H. Wang and Prof. P. Wen of Institute of Physics, Chinese Academy of Sciences. Professor W.H. Wang and P. Wen will be the local host of the workshop. The workshop is supported by Sino-German Center for Research Promotion. All the participants of the workshop are invited including 10 German scientists, 21 Chinese scientists and 2 international scientists to make statement and discussion about the latest progress, developmental direction, and the connection between physics and material science in the amorphous metals field.
The main topics and contents of the workshop including (1) Plastic mechanism in metallic glasses; (2) Dynamical heterogeneity, fragility, aging and rejuvenation as well as their connection to structure. (3) The universal aspects and mechanism of glass formation. (4) The structural and electronic features and characteristics of metallic glasses as well as their relation with property. (5) Mechanism of microalloying in metallic glass formation and giant properties change;It is expected that the workshop could promote the effective collaboration between German and Chinese scientists in glass field in the future.10 German participants:
