Structural performance in molten salt environments is important for materials used for novel energy generation such as thermal solar and next generation nuclear power systems. Characterization of these materials under these operative conditions is critical for understanding their ability to resist corrosion damage. The present research aims to characterize corrosion mechanisms and mechanical degradation of an oxide-oxide ceramic matrix composite, and high entropy alloy in NaSO4-NaCl and FLiNaK molten salts under biaxial loading conditions in an inert gas environment. Corrosion penetration depth will be measured as a function of time for these materials at 1023K unloaded as well as under biaxial tensile stress imposed using a novel disc bend configuration. The results will be compared with alloy 718 and the high-entropy alloy Al0.1CrCoFeNi under these conditions.
