摘要
涉及四种以上元素的高熵合金(HEAs)作为新兴合金,为材料设计带来了范式转变。高熵合金具有前所未有的成分多样性和结构复杂性,因此具有多维的探索空间和巨大的实用潜力,同时也给合成带来了艰巨的挑战。为了进一步优化性能和促进先进应用,必须合成具有所需特性的 HEA,以满足应用场景的要求。HEA 的特性与其化学成分、微观结构和形态密切相关。本综述全面概述了 HEA 的可控合成,包括成分设计、形态控制、结构构建和表面/界面工程。文中介绍了与 HEAs 相关的基本参数和先进表征方法。我们还提出了未来发展的几个重要方向。本综述有助于深入了解 HEAs,加快合成所需的 HEAs。
High-entropy alloys (HEAs) involving more than four elements, as emerging alloys, have brought about a paradigm shift in material design. The unprecedented compositional diversities and structural complexities of HEAs endow multidimensional exploration space and great potential for practical benefits, as well as a formidable challenge for synthesis. To further optimize performance and promote advanced applications, it is essential to synthesize HEAs with desired characteristics to satisfy the requirements in the application scenarios. The properties of HEAs are highly related to their chemical compositions, microstructure, and morphology. In this review, a comprehensive overview of the controllable synthesis of HEAs is provided, ranging from composition design to morphology control, structure construction, and surface/interface engineering. The fundamental parameters and advanced characterization related to HEAs are introduced. We also propose several critical directions for future development. This review can provide insight and an in-depth understanding of HEAs, accelerating the synthesis of the desired HEAs.
