| Abstract Scope |
Alloys with a combination of good long-term corrosion performance in molten salt and high-temperature mechanical strength are required for structural components of MSRs. Two nickel-based alloys, with creep strength superior to Hastelloy-N, as well as TZM, a molybdenum-based alloy with Ti and Zr additions (<1wt.%), may be potential advanced alloys for MSR applications. The advanced alloys are evaluated for corrosion in molten FLiNaK (LiF-KF-NaF) at 700oC and compared to conventional alloys 316L and 316H stainless steels, and Hastelloy-N. The results of two concurrent experiments will be presented, namely the potentiodynamic polarization method for rapid measurements of corrosion parameters and the more long-term prototypical static corrosion tests. Comparisons of the materials will be made in terms of electrochemical performance, microstructure, and microchemistry to evaluate their suitability for deployment in MSRs. |
