我们报告的发现高熵合金（HEA）与六方晶体结构。合金系统Ho-Dy-Y-Gd-Tb中的等原子样品被发现凝固为均匀的单相HEAs。我们的电子衍射调查和高分辨率扫描透射电子显微镜的结果是一致的镁型六方结构。讨论了六方高熵合金在其它合金体系中的可能性。
We report on the discovery of a high-entropy alloy (HEA) with a hexagonal crystal structure. Equiatomic samples in the alloy system Ho-Dy-Y-Gd-Tb were found to solidify as homogeneous single-phase HEAs. The results of our electron diffraction investigations and high-resolution scanning transmission electron microscopy are consistent with an Mg-type hexagonal structure. The possibility of hexagonal high-entropy alloys in other alloy systems is discussed.
