摘要

高熵陶瓷（HECs）由于其独特的微观结构、理想的性能和广阔的组成空间而备受关注。在本研究中，我们使用自制的带有阴离子空位的TiN0.3作为助烧结剂，等量混合VN、CrN和NbN。结果表明：首先，在保温时间为5 min的情况下，成功合成了具有单一岩盐相的高熵氮化陶瓷。其次，保温时间为15 min时，样品的硬度、抗弯强度和断裂韧性分别在21.51±1.50 GPa、1271±24 MPa和3.63±0.35 MPa m1/2下达到最大值。

The Effect of Holding Time on the Properties of N-Vacancy Diffused High-Entropy Nitride Ceramics (Ti0.25V0.25Cr0.25Nb0.25)N0.825

High-entropy ceramics (HECs) have garnered significant attention due to their unique microstructure, desirable properties, and vast compositional space. In this study, we utilized homemade TiN_0.3 with anionic vacancies as a sintering aid, equimolarly mixed with VN, CrN, and NbN. Our results demonstrate the following: Firstly, high-entropy nitride ceramics with a single rock salt phase were successfully synthesized within a holding time of 5 min. Secondly, the samples exhibited their maximum hardness, flexural strength, and fracture toughness values at a holding time of 15 min-measuring at 21.51 ± 1.50 GPa, 1271 ± 24 MPa, and 3.63 ± 0.35 MPa m^1/2, respectively.

期刊介绍： Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
