摘要

在这篇文章中，我们简要地总结了短程有序(sro)的形成和表征及其对高熵合金(HEAs)变形行为的影响的实验和理论发现。研究表明，sro的存在是HEAs结构的一个共同而又关键的结构特征，调整sro的程度是优化HEAs力学性能的有效途径。此外，还讨论了高等学府中sro的形成机制和表征方面存在的挑战，并提出了未来的研究方向。

Short-range ordering and its effects on mechanical properties of high-entropy alloys

In this letter, we briefly summarize experimental and theoretical findings of formation and characterization of short-range orderings (SROs) as well as their effects on the deformation behavior of high-entropy alloys (HEAs). We show that existence of SROs is a common yet key structural feature of HEAs, and tuning the degree of SROs is an effective way for optimizing mechanical properties of HEAs. In additional, the challenges concerning about formation mechanism and characterization of SROs in HEAs are discussed, and future research activities in this regard are also proposed.
