A nickel based alloy with molybdenum, chromium and titanium (Ni–Cr-Mo-Ti alloy) has been indigenously developed for applications related to the Indian Molten Salt Breeder Rector (IMSBR). The present work involves investigation of the interaction of the above alloy with molten fluoride salt using an in-house developed Molten Salt Corrosion Test Facility (MSCTF). In a comparative study, the indigenous alloy along with other Ni based alloys, were exposed to molten fluoride salt, FLiNaK, under static conditions at 973 K (700 °C) in MSCTF. Salient results indicate that the extent of fluoride salt attack is directly proportional to the chromium content of the above alloys. In addition, the molten fluoride salt preferentially attacks the grain boundaries of the Ni–Cr-Mo-Ti alloy although the inherent carbide/nitride precipitates can also play a major role in the corrosion mechanism.
