Phase Transitions, Devitrification and Scaling Law in Metallic Glasses
Prof. John S. Tse
University of Saskatchewan, Canada; Jilin University, China

I will present results of recent theoretical studies on the effect of pressure on metallic glasses. The focus is on the discussion on the interesting phenomena, such as polyamorphism, amorphous→crystalline transformations and non-cubic scaling laws. A conclusion can be drawn by these observations leading to a new paradigm on the understanding of pressure effect on disordered metallic glasses.

About the Speaker

John S. Tse started his research career in synchrotron radiation in 1975. After receiving his Ph.D. from the University of Western Ontario 1980, he moved to the Chemistry Division of the National Research Council of Canada in Ottawa as an NSERC Fellow. He was appointed scientific officer in 1981. In 1990, he moved to the newly created NRC Steacie Institute for Molecular Science. He progressed quickly through the ranks and achieved the highest level of principal research officer in 2000. In 2004, he joined the University of Saskatchewan as a Tier One Canada Research Chair in the Department of Physics and Engineering Physics. Since moving to the university, he has focused on the superconductivity behavior of dense hydrogen alloys and magnetic single-molecule radical solids under compression. He co-discovered the first nano-molecular metal in 2012. Dr. Tse has published over 490 articles and 18 reviews and book chapters in diverse subjects. His h-index is 51 with close to 10,000 citations. He was elected to a Fellow of the Royal Society of Canada in 2008 and received the Distinguished Researcher Award of the University of Saskatchewan in 2010 and earned a D.Sc. in 2012.
