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 …

Nano-lamellar materials with ultrahigh strengths and unusual physical properties are of
technological importance for structural applications. However, these materials generally …

The novel idea of alloying, which is based on the utilization of multiple principal elements in
high concentrations, has created a novel class of promising materials called high entropy …

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 …

High-entropy alloys are a class of materials that contain five or more elements in near-
equiatomic proportions,. Their unconventional compositions and chemical structures hold …

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 …

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 …

Metals with nanocrystalline grains have ultrahigh strengths approaching two gigapascals.
However, such extreme grain-boundary strengthening results in the loss of almost all tensile …

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 …
