| Abstract Scope |
Targets and beam windows are currently the limiting factors for beam power and runtime for high energy particle accelerators performing fundamental research and isotope production at facilities such as Fermilab, CERN, etc. Thermal shock and fatigue due to beam heating are the primary modes of failure for these components, which are accelerated by irradiation damage from the beam. New materials need to be explored and studied that are capable of withstanding increased beam powers and are resistant to higher doses. In this study we have developed and manufactured novel low-density Refractory High Entropy Alloys (RHEAs) by coupling CALPHAD-based thermodynamics predictions and traditional alloying principles. Selected samples were irradiated using 4 MeV vanadium ions up to 100 dpa. Mechanical and microstructural analysis were performed on as-manufactured and irradiated-samples to evaluate their radiation resistance. |
