论文摘要
高渗透合金（HEAS）是一种新的材料，在世界范围内进行了精力研究。 HEAS的特征是多组分合金，其中五个或更多元素随机占据了晶体学位点。常规的HEACT概念已发展为简单的晶体结构，例如面部中心地带（FCC），以身体为中心的立方（BCC）和六边形封闭的填料（HCP）结构。高度原子序列的状态产生许多出色的机械或热性能。自2014年发现BCC Hea超导体以来，超导性一直是HEAS领域的重点主题之一。超导性的特征是针对原子疾病或极高压力的鲁棒性。关于HEA超导体的材料研究才刚刚开始，并且有意外发现新现象的开放可能性。本评论更新了HEA超导体的研究状态。我们调查BCC和HCP HEA超导体，并讨论简单的材料设计。 HEA的概念扩展到具有多个晶体学位点的材料。因此，我们还使用CSCL型，α-MN型，A15，NaCl-Type，σ相和分层结构引入多站点HEA超导体，并讨论了多站点HEA SUPERDOCCONTOR的材料研究。最后，我们介绍了共晶Hea超导体和牙龈金属HEA超导体的新观点。
High-entropy alloys (HEAs) are a new class of materials which are being energetically studied around the world. HEAs are characterized by a multi-component alloy in which five or more elements randomly occupy a crystallographic site. The conventional HEA concept has developed into simple crystal structures such as face-centered-cubic (fcc), body-centered-cubic (bcc) and hexagonal-closed packing (hcp) structures. The highly atomic-disordered state produces many superior mechanical or thermal properties. Superconductivity has been one of the topics of focus in the field of HEAs since the discovery of the bcc HEA superconductor in 2014. A characteristic of superconductivity is robustness against atomic disorder or extremely high pressure. The materials research on HEA superconductors has just begun, and there are open possibilities for unexpectedly finding new phenomena. The present review updates the research status of HEA superconductors. We survey bcc and hcp HEA superconductors and discuss the simple material design. The concept of HEA is extended to materials possessing multiple crystallographic sites; thus, we also introduce multi-site HEA superconductors with the CsCl-type, α-Mn-type, A15, NaCl-type, σ-phase and layered structures and discuss the materials research on multi-site HEA superconductors. Finally, we present the new perspectives of eutectic HEA superconductors and gum metal HEA superconductors.
