    THIS SECTION ADDRESSES the design, control, and interpretation of corrosion tests conducted in liquid metals. The emphasis in this chapter is placed on techniques that should be employed for determining the suitability of metals and alloys for liquid metal containment. Because one of the most important applications of liquid metal is for heat transfer, or thermal management within an engineered system, a focus will be placed on methods for study and measurement of corrosion in a circulating system in which there is a temperature gradient. Metals and alloys with relatively low melting points and high thermal conductivities are commonly used for these applications. A range of heat capacities and boiling points then permits specific selection for a variety of applications; for example, a lead system for applications below 500°C, sodium for operation up to 700°C, and lithium up to about 1300°C. The properties of potassium make it suitable for use as a working fluid in a two-phase Rankine cycle. In each case, however, the combination of liquid metal and candidate containment material requires careful evaluation before a final selection is made.
