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 these materials under operative conditions is critical for understanding their ability to resist corrosion damage. The present research aims to characterize corrosion mechanisms and mechanical degradation of the high entropy alloy Al0.1CrCoFeNi in NaSO4-NaCl molten salts under biaxial loading conditions in an inert gas environment. Corrosion penetration depth has been 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 are compared with alloy 617 and stainless steel 316 under these conditions. |
