Abstract High entropy alloys (HEAs), offering a multi-dimensional compositional space, provide almost limitless design opportunities surpassing the frontiers of structural materials development. However, an in-depth appraisal of the fundamental materials physics behind strengthening in HEAs is essential in order to leverage them to achieve greater flexibility in application oriented materials design. This viewpoint paper concentrates on issues regarding inherent compositional fluctuations in HEAs and corresponding impact on strengthening is highlighted. In particular, metal physics based design criteria in multi-phase HEAs are discussed and comparisons between multi-phase and single-phase HEAs are drawn.

高熵合金的强化机制：基本问题

摘要 高熵合金 (HEA) 提供了多维组成空间，提供了几乎无限的设计机会，超越了结构材料发展的前沿。然而，深入评估 HEA 强化背后的基本材料物理是必不可少的，以便利用它们在面向应用的材料设计中实现更大的灵活性。这篇观点论文集中讨论了有关 HEA 固有成分波动的问题，并强调了对强化的相应影响。特别是讨论了多相 HEA 中基于金属物理的设计标准，并比较了多相 HEA 和单相 HEA。
