Abstract
Metals and alloys germane to thermionic energy converter usage were screened for embrittlement by liquid cesium metal. The results of the screening evaluations are reported and techniques are described for more detailed studies of ceramics and susceptible metals. Definite reductions in tensile ductility were observed for 302 stainless steel and molybdenum. Bend ductility was lowered in the cases of unalloyed titanium, titanium-6 aluminum-4 vanadium alloy, columbium, tantalum and silver-copper eutectic solder. Some difficulty in reproducibility wetting samples was evident throughout the study. Slightly contaminating the cesium with oxygen (or water) was observed to increase cesium wettability markedly.
