| Abstract Scope |
Liquid metals continue to be of interest for fusion applications in heat transfer, tritium breeding and plasma-facing components (PFCs). For Li, liquid metal embrittlement is a concern and an initial study at 200°C showed decreased ductility with hollow F82H (Fe-8Cr-2W) specimens when Li was inside. For PFCs, Sn is attractive because of its low vapor pressure but capsule testing showed poor compatibility with F82H at 400°C. More promising results were observed with pre-oxidized FeCrAlMo at 400°C-500°C in static Sn. A flowing Sn thermal convection loop (TCL) was conducted for 1000 h with a peak temperature of 400°C. Large mass losses for pre-oxidized ODS Fe-(10-12)Cr-6Al and FeCrAlMo suggest that Sn will be challenging to use. Finally, a series of TCL experiments have been conducted with commercial Pb-17Li and FeCrAlMo. The most recent experiments included CVD SiC specimens.
