Annual Review of Materials Research, 1989
Hardmetals or cemented carbides (sometimes less accurately called sin tered carbides) are composite materials with one or more hard but rela tively brittle components and a ductile binder metal that imparts a certain degree of toughness to the composite material without impairing the high hardness of the carbide components.

Solid Solution Cermet: (Ti,Nb)(CN)–Ni Cermet
Journal of Nanoscience and Nanotechnology, 2014Solid solution powders without W, (Ti,Nb)(CN) powders with a B1 structure (NaCl like), were synthesized by high energy milling and carbothermal reduction in nitrogen. The range of molar ratios of Ti/Nb for forming complete (Ti,Nb)(CN) phase was broader than that of Ti/W for the (Ti,W)(CN) phase because carbide or carbonitride of Nb had a B1 crystal ...

Microstructure and properties of Ti(C, N)–TiB2–FeCoCrNiAl high-entropy alloys composite cermets
Materials Science & Engineering: A, 2019The FeCoCrNiAl high-entropy alloys (HEA) was used as binder of the Ti(C, N)–TiB2 composite cermets. The Ti(C, N)–TiB2–FeCoCrNiAl HEA composite cermets were successfully fabricated by mechanical alloying (MA) and vacuum hot-pressing sintering (VHPS) at ...
