Functional High Entropy Alloys

This presentation reports about recent progress in the field of high-entropy alloys that have interesting functional properties, at maintained good mechanical properties, for which some of these materials are known. Five specific topics are discussed, namely, mechanically strong and ductile high- and medium entropy alloys with good magnetic, invar, electrocatalytic, and hydrogen tolerant properties. Although these features are in part also available from other alloy systems, their combination with good mechanical properties makes them particularly attractive for future applications in fields related to sustainable energy conversion, electrification and longevity.
