| Abstract Scope |
Structural performance in molten salt environments is important for materials used in high temperature aerothermal components at marine sites and for novel energy generation such as thermal, solar, and next generation nuclear power systems. Characterization of materials under these operative conditions is critical for understanding their ability to resist corrosion damage. Ceramic matrix composites (CMCs) are a material of interest for these high-temperature corrosive environments because they are inert and offer low activation energy, thermal shock resistance and low-density. The present research aims to characterize corrosion mechanisms and mechanical degradation of Ox/Ox and C/SiC CMCs in Na2O4-NaCl molten salt under biaxial loading conditions and compare the behavior to previous work done on high-temperature alloys, including a next-generation high entropy alloy Al0.1CrCoFeNi. Depletion zone depth has been measured as a function of time for these materials at 750°C under biaxial stress imposed using a novel disc bend configuration. |
