无序增强了所需的性能，同时也为合成材料创造了新的途径。例如，通过固溶强化提高硬度和屈服应力，这是变形和原子尺寸失配的结果。热化学稳定性增加的优先选择的化学无序的混合物的高对称性的超晶格。振动热导率降低力常数无序，而不牺牲机械强度和刚度。因此，高熵陶瓷推动了广泛的应用：从耐磨涂层和热和环境屏障到催化剂，电池，热电和核能管理。在这里，我们讨论了该领域的最新进展，特别强调无序增强的性质和应用。
Disorder enhances desired properties, as well as creating new avenues for synthesizing materials. For instance, hardness and yield stress are improved by solid-solution strengthening, a result of distortions and atomic-size mismatches. Thermochemical stability is increased by the preference of chemically disordered mixtures for high-symmetry superlattices. Vibrational thermal conductivity is decreased by force-constant disorder without sacrificing mechanical strength and stiffness. Thus, high-entropy ceramics propel a wide range of applications: from wear-resistant coatings and thermal and environmental barriers to catalysts, batteries, thermoelectrics, and nuclear energy management. Here, we discuss recent progress of the field, with a particular emphasis on disorder-enhanced properties and applications.
