High-entropy alloys (HEAs) have attracted extensive interest due to their exceptional
mechanical properties and the vast compositional space for new HEAs. However …

Research in the field of high-entropy alloys has been surging since the 2010s. As widely
acknowledged, research interests in this field are largely sparked by the enormous …

The high-entropy alloy (HEA) concept was based on the idea that high mixing entropy can
promote formation of stable single-phase microstructures. During the past 15 years, various …

Traditional metallic alloys are mixtures of elements in which the atoms of minority species
tend to be distributed randomly if they are below their solubility limit, or to form secondary …

Alloying has long been used to confer desirable properties to materials. Typically, it involves
the addition of relatively small amounts of secondary elements to a primary element. For the …

Abstract High-entropy alloys (HEAs), also known as multi-principal element alloys or multi-
component alloys, have been the subject of numerous investigations since they were first …

Multiprincipal-element alloys are an enabling class of materials owing to their impressive
mechanical and oxidation-resistant properties, especially in extreme environments,. Here …

High-entropy and medium-entropy alloys are presumed to have a configurational entropy as
high as that of an ideally mixed solid solution (SS) of multiple elements in near-equal …

Conventional alloys are usually based on a single host metal. Recent high-entropy alloys
(HEAs), in contrast, employ multiple principal elements. The strength of HEAs is …

We revisit the meaning of stacking fault energy (SFE) and the assumptions of equilibrium
dissociation of lattice dislocations in concentrated alloys. SFE is a unique value in pure …
