摘要

Alloying strategies have proven effective in enhancing the properties of metallic materials. However, conventional alloying strategies face significant limitations in preparing nanoscale multi-alloys and continuous optimizing surface-active sites. High-entropy alloys (HEAs) display a broader spectrum of unique properties due to their complex electron distribution and atomic-level heterogeneity arising from the stochastic mixing of multiple elements, which provides a diverse array of binding sites and almost continuous distribution of binding energies. This review aims to summarize recent research advancements in synthesis strategies and multi-field applications of nanoscale HEAs. It emphasizes several commonly employed synthesis strategies and significant challenges in synthesizing nanoscale HEAs. Finally, we present a comprehensive analysis of the advantages of HEAs for multi-field applications, emphasizing significant application trends related to nanosizing and multidimensionalization to develop more efficient nanoscale HEAs.
