High‐entropy carbide‐based ceramic cutting tools
Journal of the American Ceramic Society, 2022Abstract In this study, a novel high‐entropy carbide‐based ceramic cutting tool was developed. The cutting performance of three kinds of high‐entropy carbide‐based ceramic tools with different mechanical properties for the ISO C45E4 steel were evaluated. Although the pure (Ti 0.2

High-entropy sesquioxide X2O3 upconversion transparent ceramics
Scripta Materialia, 2020Abstract In this study, a high-entropy approach was used to design a highly transparent (81.3% in-line transmittance) sesquioxide X2O3 ceramics, in which a single-phase solid solution, with the general formula (Lu0.2Y0.395Gd0.2Yb0.2Tm0.005)2O3, was obtained after sintering under vacuum with La2O3 and ZrO2 as the sintering additives.

Processing of dense high-entropy boride ceramics
Journal of the European Ceramic Society, 2020Abstract Dense (Hf0.2,Zr0.2,Ti0.2,Ta0.2,Nb0.2)B2 high-entropy ceramics with high phase purity were produced by two-step spark plasma sintering of precursor powders synthesized by boro/carbothermal reduction of oxides. The reacted powders had low oxygen (0.404 wt%) and carbon (0.034 wt%) contents and a sub-micron average particle size (∼0.3 μm ...
