"Engineering Microstructure and Composition of Materials

to Enhance Properties for Nuclear Applications"

ABSTRACT:

There are critical societal needs to have clean energy, improve energy efficiency, and enhance the safety and reliability of energy systems. Nuclear energy is an important form of clean energy and plays a notable role in decarbonizing the economy and combating the climate change. Materials used in nuclear reactors are subjected to severe damages by the extremely harsh environments, including intense irradiation, high temperature, high mechanical stress, and corrosive atmosphere. Life extension of current nuclear reactors and development of next-generation nuclear reactors require more robust materials with enhanced properties and performance. There are two approaches to enhancing irradiation resistance: 1) engineering microstructure of existing materials, and 2) developing new materials. In this talk, research projects will be discussed involving nano science and engineering in an effort to manufacture and evaluate nanostructured steels with enhanced mechanical properties and irradiation resistance (steels are the most used materials in nuclear reactors). New materials, specifically high-entropy alloys, have also been developed, fabricated using different manufacturing techniques, and assessed for mechanical properties, high temperature stability and irradiation performance. The microstructures of the materials are tailored on the nanometer scale in order to achieve enhanced properties. Finally, oxidation of nuclear fuels, as well as additive manufacturing of nuclear structural materials, will also be briefly discussed in this talk.

BIOGRAPHY:

Dr. Wen is an Assistant Professor in the Department of Materials Science and Engineering and Department of Nuclear Engineering and Radiation Science at Missouri University of Science and Technology (Missouri S&T). He obtained his PhD from University of California – Davis in 2012, and subsequently held postdoctoral appointments at Northwestern University and Idaho National Laboratory. Prior to joining Missouri S&T, he was a Research Assistant Professor at Idaho State University and a staff scientist at Idaho National Laboratory. Dr. Wen has extensive experience in research and development of advanced materials, especially those for nuclear applications. He has been leading multiple research projects funded by the Department of Energy, National Science Foundation, and Nuclear Regulatory Commission. Dr. Wen has authored or coauthored more than 65 peer-reviewed journal publications, with citations >3,400 and an h-index of 25. He serves on the Editorial Board of the journal Materials Science and Engineering A and has served as the lead guest-editor of a special issue in AIMS Materials Science. He regularly reviews manuscripts for many journals and research proposals for DOE and NSF. He was named CEC Dean’s Scholar and received an Outstanding Teaching Award from Missouri S&T in Dec. 2022.
