Many of the HEAs contain cobalt, which is not a desirable material for in-core nuclear reactor applications due to the neutron-induced transmutation to produce °Co that can make some plant maintenance activities more difficult (due to normal corrosion processes that cause atomic deposition of core materials throughout the primary coolant loop, particularly in the cooler regions). Some single-phase HEAs with attractive mechanical properties that do not contain cobalt have been manufactured [116]. Tensile properties for a single-phase fee high-entropy alloy are summarized in Fig. 16.6.
