Nature Reviews Materials, 2019 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 past decade and a half, however, a new alloying strategy that involves the combination of multiple principal elements in high concentrations to create new materials ...

Multicomponent and High Entropy Alloys [PDF]
Entropy, 2014 This paper describes some underlying principles of multicomponent and high entropy alloys, and gives some examples of these materials. Different types of multicomponent alloy and different methods of accessing multicomponent phase space are discussed ...

Corrosion of high entropy alloys [PDF]
npj Materials Degradation, 2017 High entropy alloys represent a unique class of metal alloys, comprising nominally five or more elements in near equiatomic proportions. High entropy alloys have gained significant interest on the basis that the high configurational entropy of such alloy

Advances in Materials Science and Engineering, 2015 Most metallic alloys contain small concentrations of solutes because they are sufficient to achieve amazing properties on a grand scale of production and utilisation. In the early 1980s, a different concept was introduced that involved mixing large concentrations of solutes in roughly equal amounts so that there is no predominant solvent.

High-Entropy Alloys (HEAs) [PDF]
Metals, 2018 High-entropy alloys (HEAs) [1,2] loosely refer to multi-principal-element solid solution alloys due to their high configurational entropy, in contrast to traditional alloys, which focus on the edge or corner of phase diagrams with one principal component[

Nanoprecipitate‐Strengthened High‐Entropy Alloys [PDF]
Advanced Science, 2021 Multicomponent high‐entropy alloys (HEAs) can be tuned to a simple phase with some unique alloy characteristics. HEAs with body‐centered‐cubic (BCC) or hexagonal‐close‐packed (HCP) structures are proven to possess high strength and hardness but low ...

Effect of valence electron concentration on stability of fcc or bcc phase in high entropy alloys [PDF]
, 2011 Phase stability is an important topic for high entropy alloys (HEAs), but the understanding to it is very limited. The capability to predict phase stability from fundamental properties of constituent elements would benefit the alloy design greatly.
