In conjunction with studies of the suitability of liquid metals for high‐temperature heat‐transfer systems, an investigation was made to determine the resistance of forty materials–eighteen ceramics and cermets, thirteen refractory metals, and nine high‐temperature alloys–to attack by Pb‐Bi eutectic alloy (44.5% Pb and 55.5% Bi) in a dynamic system at temperatures of 1500° or 2000°F. The experimental apparatus and procedure is described. With the exception of ZrC all the ceramics and cermets were resistant to attack by molten Pb‐Bi eutectic at 2000°F. Of the thirteen refractory metals only arc‐cast molybdenum exhibited resistance to Pb‐Bi at 2000°F. All nine of the high‐temperature alloys had poor resistance at 1500°F.
