The expansion of programmatically-accessible materials data has cultivated opportunities for data-driven approaches. Highly-automated frameworks like AFLOW not only manage the generation, storage, and dissemination of materials data, but also leverage the information for thermodynamic formability modeling, such as the prediction of phase diagrams and properties of disordered materials. In combination with standardized parameter sets, the wealth of data is ideal for training machine learning algorithms, which have already been employed for property prediction, descriptor development, design rule discovery, and the identification of candidate functional materials. These methods promise to revolutionize the path to synthesis and, ultimately, transform the practice of traditional materials discovery to one of rational and autonomous materials design.

所有生物有机体,从植物到生物,都可以治愈轻微的伤口和损伤。几十年来,在无机材料中实现类似的自愈能力一直是设计目标。这将代表材料工程的突破,使许多新的技术应用成为可能,因为这种材料将能够抵抗电磁辐射和/或机械冲击造成的损害。在这里,我们证明了高熵氧化物本质上能够进行自主的自我修复过程。透射电子显微镜显示,尖晶石结构的(AlCoCrCu0.5FeNi)3 O 4可以再生,并在原子水平上修复损坏时。密度泛函理论计算揭示,在制造过程中存储在高熵材料中的额外焓可以被释放,以通过重新生长成部分有序状态来有效地修复宏观缺陷。这种非凡的自修复现象使这种新材料非常适合作为涂层,使在恶劣环境中使用的结构能够更好地承受损坏,例如太空中的宇宙辐射,核电设施中的核辐射或摩擦学损坏。最重要的是,我们的研究结果为自修复材料的合成提供了一般的设计原则。
