High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements. Prior to the synthesis of these substances, typical metal alloys comprised one or two major components with smaller amounts of other elements.

Jun 18, 2019 · Here, we review recent progress in understanding the salient features of high-entropy alloys. Model alloys whose behaviour has been carefully investigated are highlighted and their...

Jul 1, 2016 · High-entropy alloys (HEAs) are presently of great research interest in materials science and engineering. Unlike conventional alloys, which contain one and rarely two base elements, HEAs comprise multiple principal elements, with the possible number of HEA compositions extending considerably more than conventional alloys.

Apr 15, 2020 · In the large pool of alloys with varying characteristics, the first single-phase HEA with good tensile properties, the equiatomic CrMnFeCoNi alloy has become the benchmark material, and it forms the basis of much of our current fundamental understanding of HEA mechanical behavior.

Apr 30, 2014 · 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 book provides a systematic and comprehensive description of high-entropy alloys (HEAs). The authors summarize key properties of HEAs from the perspective of both fundamental understanding and applications, which are supported by in-depth analyses.

High entropy alloys (HEAs) are generally defined as a solid solution with five or more principal elements that have a large concentration of 5–35 at%, possessing a high mixing entropy (Tsai and Yeh, 2014; Yeh et al., 2004).

May 19, 2023 · Herein, based on high-throughput density-functional theory calculations, we construct a chemical map of single-phase equimolar high-entropy alloys by investigating over 658,000 equimolar...

1 day ago · High-entropy alloys (HEAs) are alloys that consist of five or more principal elements in near-equiatomic proportions that tend to form simple solid solutions during solidification owing to high mixing entropy. HEAs have been identified as promising candidates for various heterogeneous catalysis and electrocatalysis applications. This work illustrates the utility of time-of-flight secondary ion ...

Apr 18, 2019 · Decades-long, intensive international efforts to develop new materials are failing. These include efforts towards improved high temperature alloys for energy production and aerospace propulsion...
