Cemented carbides combine the high hardness and strength of metallic carbides (WC, TiC, TaC) or carbonitrides (eg TiCN) with the toughness and plasticity of a metallic alloy binder (Co, Ni, Fe), in which the hard particles are evenly distributed to form a metallic composite. Tungsten carbide is the most metallic of the carbides, and by far the most important hard phase. The more hard carbide

Coated cemented carbide is one of suitable tool material to cutting of Ti6Al4V alloy beside CBN tools, HSS tools and cutting ceramics. The carbide with coating based on TiN, TiCN or TiAlN
Cemented carbide represents a class of composite materials, consisting of hard and wear resistant carbide and a tough and ductile metal binder, and thus owns a unique combination of hardness and toughness. In order to increase the performance and extend the service lifetime of the cemented carbides, graded cemented carbides have been developed. The formation of gradient zone during
Jan 04, 2020#0183;#32;4 January, 2020. Cemented carbide is the most widely used high speed machining (HSM) tool material. This kind of material is produced by powder metallurgy process, which is composed of cemented carbide (usually tungsten carbide WC) particles and soft metal bond. At present, there are hundreds of different components of WC based cemented carbides, most of them use Cobalt (CO)
In one aspect, cemented carbide bodies are provided. A cemented carbide body described herein, in some embodiments, comprises a tungsten carbide phase, a binder phase comprising at least one metal of the iron group or an alloy thereof, a solid solution phase of carbides of zirconium and niobium (Zr,Nb)C and cubic carbides in an amount ranging from about volume percent to about 6 volume

January 1937 THERMAL EXPANSION OF CEMENTED TUNGSTEN CARBIDE By as alloy steels, bronzes, hard rubbers, and fibrous materials. In cutting operations, temperature changes affect the tool and the work. This material, because of its low thermal expansion, undergoes small dimensional change during such operations as cutting and grinding. A knowledge of the thermal expansion of cemented

01/01/2019#0183;#32;The influence of Cr 3 C 2 doping on the sintering process and mechanical properties of WCCo cemented carbides was studied. Using differential thermal analysis of green powders and thermodynamic calculations, the disappearing temperature of solidstate binder phase in the ultrafine WCCo cemented carbides with different amounts of Cr 3 C 2 dopant was first investigated and then
