Alloyed Pleasure: Multi-metallic cocktails

The rapid progress of technology during the last 50 years and the increasing demand during the 21st century have put tremendous pressure on materials scientists to develop newer and further improved materials that have higher strength or improved stiffness as well as materials that could be used at a much higher temperature and in more adverse environments than is possible with commercially available materials as of today. These efforts resulted in the design and development of advanced materials that are “Stronger, Stiffer, and Lighter” and also those that could be used at much higher temperatures (“Hotter”) than the existing materials. The synthesis and development of such materials have been facilitated by exploring “multicomponent alloys”. For example, metals are mixed in a multi-metallic cocktail to make bulk metallic glasses, multi-functional, superelastic and superplastic alloys and, recently, high entropy alloys. Furthermore, in order to achieve a combination of properties and performance better than those of the existing materials, it is critical to combine processing variables that can be used to create materials that are far from equilibrium. Indeed, the metastable multi-metallic cocktails provide the opportunity to develop completely new materials. This seminar will review my group’s research topics, which will provide a glimpse at the cutting edge of advanced metallic materials research and beyond. Multi-metallic cocktailscreated that are far from equilibrium hopefully will lead to the beginning of a new era in metallic materials.

Eun Soo Park received his Ph.D. in Metallurgical Engineering from Yonsei University, Korea, in 2005 and worked as a postdoctoral fellow in the Department of Applied Physics at Harvard University until 2008. Afterwards he joined the Department of Materials Science and Engineering at Seoul National University in 2008 as an Assistant Professor and was promoted to Associate Professor in 2012 and Professor in 2018. Professor Park has been a visiting fellow at several universities and institutes, such as National Institute for Materials Science (2004, Japan), Tohoku University (2012, Japan), IFW Dresden (2005, 2014, Germany), MPIE Dusseldorf (2015, Germany), Indian Institute of Science Bangalore (2015, India), and, most recently, Lawrence Berkeley National Laboratory (2013-2018 & 2022-present, United States). He received the Young Leader Academic Award from the Korean Institute of Metals and Materials (2012) as well as an outstanding symposium paper award in 2007 and 2010 MRS fall meetings and is selected to be a winner of 2016 TMS SMD Young Leaders Professional Development Award and a Prime Minister’s Commendation for Innovative Inventions (Korea, 2019). He is on the editorial advisory board for Communications Materials and Transactions of The Indian Institute of Metals. He is an expert on the physical metallurgy and mechanical behavior of bulk metallic glasses, high entropy alloys and advanced engineering materials. His research interests are in the tailor-made materials design and microstructure-property relationships in metallic materials. He has authored more than 137 publications (115 SCI(E) and 23 domestic) in respectable peer-reviewed journals including Progress in Materials Science, Nature Communications, Acta Materialia, Materials & Design and Applied Physics Letters, several of which have garnered international recognition. In addition, he has also published more than 95 patents (16 international and 79 domestic) and 1 chapter of a technical book. According to Google Scholar, the total citation of his papers reaches about 4630, and his H index is 35.
