Abstract Fatigue resistance is a crucial requirement to the novel high-entropy alloys when they come to engineering applications, as many metal structures used in practice are failed by cyclic loading. Here, a thorough analysis of the information on the low-cycle fatigue, high-cycle fatigue, crack-growth rates, and fatigue mechanisms in the high-entropy alloy literature unveils a guideline through which the discovery and design of fatigue-resistant high-entropy alloys can be facilitated. Overall, multi-phase alloys, particularly the metastable ones, are favorable to fatigue resistance over single-phase alloys. Suggestions are proposed in the end to accelerate the discovery and design of candidates for fatigue-resistant applications.

抗疲劳高熵合金的发现与设计

摘要 抗疲劳性是新型高熵合金在工程应用中的关键要求，因为在实践中使用的许多金属结构都因循环载荷而失效。在这里，对高熵合金文献中关于低周疲劳、高周疲劳、裂纹扩展率和疲劳机制的信息进行彻底分析，揭示了发现和设计抗疲劳高周疲劳的指南。可以促进熵合金。总的来说，多相合金，特别是亚稳态合金，比单相合金有利于抗疲劳。最后提出建议，以加快发现和设计抗疲劳应用的候选物。
