Abstract
High entropy alloys (HEAs) were developed for their desirability of strength, hardness, and corrosion, wear, and radiation resistance. This makes them ideal for nuclear applications in advanced reactors. High entropy alloys are characterized as alloys containing at least 5 principal elements, each with an atomic percentage between 5 and 35% [1]. A process for fabrication and characterization of these alloys entails ball milling and spark plasma sintering (SPS), then characterization tools such as x-ray diffraction (XRD) and scanning electron microscopy (SEM).
