| Abstract Scope |
Nuclear energy is quickly reemerging as a major player in the global energy market. New materials will be needed to fuel this sector, especially as fusion energy dominates current research. Oxide Dispersion Strengthened (ODS) alloys are leading candidate materials in nuclear applications, such as cladding and structural components. Currently, the USA is still lacking in large-scale production of ODS alloys, which presently involves multi-step powder metallurgy processing. Our research investigates a metastable high entropy alloy and yttria oxide (Y2O3) composite as a structural material well suited for exposure to the extreme conditions present in nuclear reactors. Through our experimentation, this material has shown to be ideal for additive manufacturing via laser powder bed fusion. High entropy alloy’s exceptional thermal and mechanical stability combined with radiation resistance provided by yttria oxide is emerging as a promising material for nuclear. |
