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 …

Engineering metallic materials are an essential class of materials for a variety of industrial
applications due to their competitive mechanical properties, especially strength and ductility …

In this work, we designed heterogeneous (NiCoCr) 88 Al 10 Ta 2 (at.%) duplex medium-
entropy alloy (MEA) comprising the face-centered-cubic (FCC) matrix and the B2 phase …

Alloy design based on single–principal-element systems has approached its limit for
performance enhancements. A substantial increase in strength up to gigapascal levels …

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 …

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 …

Ever-harsher service conditions in the future will call for materials with increasing ability to
undergo deformation without sustaining damage while retaining high strength. Prime …

High entropy alloys (HEAs) have five or more principal elements with four core effects: high
entropy, sluggish diffusion, severe lattice distortion, and cocktail effects. These effects lead to …
