The structural and chemical microinhomogeneity of the high-entropy TiVZrNbHfTa coating is studied. Electron microprobe analysis shows that the content of elements varies within 10 at.% at a distance of several nanometers. The density of (s + d) electrons remains constant. High-resolution electron microscopy used to examine the fine structure found clusters with the size close to the ‘periodicity’ of the chemical inhomogeneity.

高熵 TiVZrNbHfTa 涂层的结构和化学微不均匀性

研究了高熵 TiVZrNbHfTa 涂层的结构和化学微不均匀性。电子微探针分析表明，元素含量在几纳米的距离内变化在 10 at.% 以内。(s + d) 电子的密度保持不变。用于检查精细结构的高分辨率电子显微镜发现团簇的大小接近化学不均匀性的“周期性”。
