Symposium Composite Materials for Nuclear Applications
Presentation Title Tungsten-based High and Medium Entropy Alloys and Composites for Nuclear Applications

On-Site Speaker (Planned) Ho Jin Ryu
Abstract Scope Tungsten-based alloys and composites have been studied for fusion plasma facing materials in order to improve the physical properties of pure tungsten under extreme environments. Recently, the concept of high entropy alloys or concentrated solid solution alloys was proposed for the irradiation resistant matrix materials. High entropy alloy based composites were designed, fabricated by using powder metallurgy processing in order to characterize the thermal properties, mechanical properties, irradiation resistance and oxidation properties. The effects of the composition of the high and medium entropy alloys and the configuration of pure tungsten-based reinforcement have been analyzed.
