High-Entropy Alloys: A Critical Review

Abstract: High-entropy alloys (HEAs) are alloys with five or more principal elements. Due to the distinct design concept, these alloys often exhibit unusual properties. Thus, there has been significant interest in these materials, leading to an emerging yet exciting new field. This paper briefly reviews some critical aspects of HEAs, including core effects, phases and crystal structures, mechanical properties, high-temperature properties, structural stabilities, and corrosion behaviors. Current challenges and important … Show more

“…However, due to the sluggish kinetic at low temperatures and incoherency between Bcc matrix and intermetallic precipitates no second phase was observed in the as-cast alloy. The density of the alloy produced in Ref 31 was measured to be 5.06 g/cm 3 , verifies our calculated value of 5.04 g/cm 3 .…”

“…This tremendous potential has driven an explosive increase of interest in HEAs in recent years as reviewed in the recent publications. [3][4][5] Obviously the exploration of new HEAs in the multi-dimensional composition space cannot rely on Edisonian approach. It requires a more efficient and systematical strategy.…”

“…The four core effects of the HEAs, that is, high configuration entropy, sluggish diffusion, cocktail effect, and large lattice distortion [2], lead to their promising properties, such as high strength and ductility, good corrosion resistance, and superior fracture toughness [3][4][5].…”
