“…At a temperature of 1600 • C and above, the (W, Ti, V)C solid solution is formed. Numerous studies have shown that carbides form solid solutions with WC, which have excellent effects on promoting the densification of WC-based materials and can improve the mechanical properties of the materials [17][18][19] . A similar densification mechanism was found in the WC-VC system by Huang et al, 20 VC formed a (V, W)C solid solution with WC, so that the WC-VC ceramics could be densified at a lower sintering temperature compared to pure WC.…”

The medium-entropy carbide (W,Ti,V)C 0.8 ceramics were prepared by sparking plasma sintering at temperatures between 1400 and 1700 • C. The effects of sintering temperature on the microstructure and mechanical properties of the medium-entropy carbide (W,Ti,V)C 0.8 ceramics were investigated. X-ray diffraction, scanning electron microscope, and energy dispersive spectrometer were used to confirm the formation of single-phase face-centered cubic (FCC) solid solution of the medium-entropy carbide (W,Ti,V)C 0.8 ceramics prepared at a sintering temperature of 1600 • C. It was found that the mechanical properties of the material were improved by solid solution strengthening during the formation of single-phase FCC solid solution, and the best overall performance of the medium-entropy carbide (W,Ti,V)C 0.8 ceramics was achieved at 1600 • C, when the hardness value was 22.3 ± 1.8 GPa, the fracture toughness was 5.7 ± 0.8 MPa⋅m 1/2 , the flexural strength was 605 ± 4 MPa, and the compressive strength was 1.84 GPa. Most importantly, the addition of TiC 0.4 promoted the diffusion among the elements of the medium-entropy carbide (W,Ti,V)C 0.8 ceramics, which contributed to the formation of single-phase FCC solid solution and significantly reduced the sintering temperature of the medium-entropy carbide (W,Ti,V)C 0.8 ceramics due to the effect of vacancies. This study provides a new idea for the preparation of medium-entropy carbide ceramics.

“…The stabilization of Cr-rich precipitates can be reduced substantially by adding alloying elements that form carbides and/or nitrides that are more stable than those formed by chromium. A strong carbide-forming element such as Ti, Nb, Zr, Ta, and V can serve as a stabilizing agent [39][40][41][42][43]. The addition of these elements to steel, especially Nb, Ti, and Ta results in stable MC-type carbides or carbon-nitrides that effectively reduce Cr-rich precipitate J o u r n a l P r e -p r o o f Journal Pre-proof formation [44][45][46].…”

“…Because of its high hardness, excellent wear resistance, low coefficient of friction, and good chemical stability, Ti(C,N)-based cermet has become an important alternative material to cemented carbide and is widely used in cutting and grinding tools [13][14][15][16][17]. However, the traditional Ni, Co, and Fe binder phases are prone to softening at high temperatures [18], leading to rapid tool wear and oxidation [19] and reducing the service life of cermets. Therefore, the development of a new binder to improve the performance of Ti(C,N)-based cermets has become a hot spot in current research [20][21][22].…”

Ti(C,N)-based cermet is a kind of composite material composed of a metal binder phase and a Ti(C,N)-hard phase, which is widely used in the fields of cutting machining and wear-resistant parts due to its high hardness, good toughness, wear resistance, and chemical stability. In recent years, the research on the replacement of traditional Ni, Co, and Fe binder phases by novel binder phases such as intermetallic compounds and high-entropy alloys has made remarkable progress, which significantly improves the mechanical properties, wear resistance, corrosion resistance, and high-temperature oxidation resistance of Ti(C,N)-based cermets. This paper reviews the latest research results, summarizes the mechanism of the new binder to improve the performance of metal–ceramics, and looks forward to the future research directions.
