Fig. 4
Assessment of HEAs for potential high-temperature applications (BCC-type HEAs, RHEAs, BCC/B2 RSAs, and FCC/L12 HESAs vs Ni-based superalloys). The x-axis provides the maximum operating temperature, with the HEA data randomly placed around an arbitrary high ‘ambition’ temperature that reflects the goals pursued in RHEA research. Yeh’s HESAs are outlined in yellow, Senkov’s RHEAs in green. Higher indicator values are undesirable. Embodied Energy is given on the y-axis. Symbol size shows Human Health Damage (HHD) and color gives the Supply Risk (SR).
