Abstract Recent researches in the field of high-entropy materials reveal an intriguing result: the multi-component systems combining the chemical elements with diverse valencies and radii can form single-phase solid solutions with the structure of intermetallic Laves phases. Here we report the fabrication of hexagonal Laves phase (C14, prototype MgZn 2 ) in duodenary TiZrHfNbVCrMoMnFeCoNiAl alloy. The phase is stable after the thermal treatment at 973 K for 50 h. To characterize the material, we examine its electrical conductivity and magnetic properties. The measurements reveal that the Laves phase is a Curie-Weiss paramagnet, which demonstrates metallic conduction and a pronounced Kondo-like anomaly at 80 K. Analysis of experimental data as well as ab initio calculations suggests that chemical complexity and compositional disorder cause strong s-d band scattering and thus the rather high density of d -states in the conduction band.

稳定的高熵 TiZrHfNbVCrMoMnFeCoNiAl Laves 相

摘要 高熵材料领域的最新研究揭示了一个有趣的结果：具有不同价态和半径的化学元素结合的多组分体系可以形成具有金属间拉夫斯相结构的单相固溶体。在这里，我们报告了在十二指状 TiZrHfNbVCrMoMnFeCoNiAl 合金中制造六角 Laves 相（C14，原型 MgZn 2 ）。该相在 973 K 下热处理 50 小时后稳定。为了表征材料，我们检查了其导电性和磁性。测量结果表明，Laves 相是居里-魏斯顺磁体，在 80 K 时表现出金属传导和明显的类似近藤的异常。
