| 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 are needed capable of withstanding increased beam powers and are resistant to higher radiation doses for prolonged life. In this study, several novel low-density single phase body centered cubic (BCC), and multiphase BCC/B2, Refractory Compositionally Complex Alloys were designed by combining CALPHAD predictions and traditional alloying principles and cast. Samples were irradiated up to 50 dpa using self-ion irradiation as well as up to 0.45 dpa using 36 MeV Ar. Samples were characterized with nanoindentation and (S)TEM to evaluate their mechanical properties and radiation resistance relative to currently used alloys. |
