Compatibility of refractory metals and beryllium with molten Pb17Li

Investigation of Pb–Li compatibility issues for the dual coolant blanket concept

“…1(c)) are not likely from the Mo capsule, but from the alloy itself, Table 1. Other experiments with 316 specimens and stainless steel or carbon steel capsules for the same time and temperature [16,19] also showed Mo-rich particles in the outer layer consistent with the dissolution resistance of Mo [10].…”

“…Contact of Fe-or Ni-base, alloys with flowing Pb-Li at $700°C would result in unacceptably high dissolution rates [3,4,9]. Although the use of refractory metals is one option, [10] fabrication and durability of Nb or Mo tubing could be an issue. A protective coating could allow a conventional Fe-or Ni-base tubing alloy to be used.…”

Corrosion behavior of CLAM steel in static and flowing LiPb at 480°C and 550°C

“…3b), so the corrosion of CLAM steel was almost not affected by the Fe-Cr steel crucible. Compared with Ni, Fe and Cr etc., the solubility of Mo in LiPb is very low [21], so the dissolution and diffusion of metallic elements from CLAM samples may be enhanced during the mass transfer (Fig. 3c), so the corrosion of CLAM specimens in Mo crucible is more serious compared with that obtained in 304S and Fe-Cr crucible.…”

Performance of a hydrogen sensor in Pb–16Li

“…Niobium and pure iron were selected as the most promising materials because they have high hydrogen diffusivity and their chemical compatibility with the lead lithium alloy is very good [3,4].…”

“…A summary and a complete list of references of the existing data of hydrogen transport parameters for several materials is reported in [2]. Results on compatibility studies between Pb-16Li and different metals and alloys are available in [3][4][5].…”
