5th Metals Webinar
High-Entropy Alloys with Special Microstructures and Unique Properties
Today we have three talks about high-entropy alloys. Our first speaker is Professor Yu Qian from Zhejiang University, who is focused on the micro- and nano-structures of high-entropy alloys. Our second speaker is from Taiyuan University of Technology, Professor Qiao Jun Wei, whose main research topic is the dynamic and cryogenic behavior of high-entropy alloys. The third speaker is from NOVA University Lisbon, Caparica, Portugal, Professor João Pedro Oliveira, who is focused on the welding of shape memory alloys.
Date: 10 January 2023

Yong Zhang obtained his PhD in 1998. He was a postdoctoral fellow at the Institute of Physics, Chinese Academy of Science; a research fellow in the Singapore-MIT Alliance, National University of Singapore; and was promoted to be a full professor in the University of Science and Technology Beijing (USTB). He is currently a flexible appointed professor in the North Minzu University. He and his group members prepared the first single-crystal, high-entropy alloys, Al0.3CoCrFeNi and Al0.3CoCrFeNi2. The invention of trace rare earth elements can improve the glass-forming ability (GFA) of amorphous alloys, which have been widely used in academia and industries. He put forward the balance ratio parameter of information entropy and mixing enthalpy to evaluate the disorder in materials, which has been proven by a large number of documents to be effective in predicting the formation of random solid solution and amorphous phases.

Yu earned her PhD degree in materials science and engineering from the University of California at Berkeley in 2012. She was a postdoctoral researcher at the National Center for Electron Microscopy at Lawrence Berkeley National Lab and UC Berkeley from 2012 to 2014. She joined the faculty of the Center for Electron Microscopy at Zhejiang University in 2014, where she is also a professor in the Department of Materials Science and Engineering. Yu is interested in materials characterization. Specifically, her research interests focus on applying in situ electron microscopy techniques to probe into the correlations between the structures and properties of materials. Her research work has been published in Nature, Science, Nature Materials, Nature Communications, etc. Qian has given more than 30 invited presentations at international conferences, including MRS, TMS, and M&M. Her current interest is in titanium alloys and high-entropy alloys.

João Pedro Oliveira is currently an assistant professor at the Materials Science Department of FCT/NOVA, Portugal. Prior to his current appointment at FCT/NOVA, he was a postdoctoral researcher at the Welding Engineering program of Ohio State University, United States of America. He earned his PhD in the laser welding of shape memory alloys at FCT/NOVA, while being a visiting researcher at the Center of Advanced Materials Joining of the University of Waterloo, Canada. His research interests focus on welding and fusion-based additive manufacturing of advanced engineering materials, with special scientific interest in less conventional engineering alloys such as shape memory and high-entropy alloys. His research group is also heavily invested in the use of high-energy synchrotron X-ray diffraction for fine probing of the material microstructure ex situ or in situ. He currently supervises 10 PhD students in the areas of welding and additive manufacturing. He is also an Associate Editor of Additive Manufacturing (Elsevier).
