“…The metallic HEAs include the Cantor-based, which consists of the FeCoNiMnCr series and refractory alloys, composed of elements such as Ti, Mo, Ta, Zr, Hf, V, Nb, etc., having improved mechanical properties, being designed for high-temperature applications and corrosive environments. The ceramic HEAs consist of metal nitrides and carbides of transition elements, possessing high strength, thermal stability, and good corrosion resistance [ 195 , 196 ].…”
