Corrosion performance of Ni-16%wt.Mo-X%wt.SiC alloys in FLiNaK molten salt

•Amount of Mo2C precipitates is proportional to the amount of SiC in the initial powder mixture.•Mo2C precipitates readily dissolve into FLiNaK molten salt leaving behind empty voids.•The corrosion resistance of NiMo-SiC alloys is strongly dependent on the amount of SiC in the initial powder mixture...
