Abstract. Cemented carbides (or hardmetals) can be conveniently defined in terms of microstructure: They consist of single crystals of one or more carbide phases which form a continuous skeleton the free space of which is filled by a continuous metal binder. This book embraces the entire range of problems associated with phase equilibria in “tungsten – carbon” binary system and related ternary systems, nonstoichiometry, disorder and order in different tungsten carbides, electronic and crystal structure of these main application of tungsten.

The cemented carbides are a range of powder-metallurgical composite materials, which consist of hard carbide particles bonded together by a metallic binder (Sandvik Hard Materials ).The proportion of carbide phase is generally between 70 % and 97 % of the total weight of the composite and its grain size averages between and 10 μm.

It is divided into 18 chapters covering wide areas from crystal structure to phase equilibria, production of metal and carbide powders, and much more. Written by an international expert, this book covers the processing, microstructure, and properties of cemented tungsten carbides.
It is divided into 18 chapters covering wide areas from crystal. Cemented carbides belong to a class of hard, wear-resistant, refractory materials in which the hard carbide particles are bound together, or cemented, by a soft and ductile metal binder.
The performance of cemented carbide as a cutting tool lies between that of tool steel and cermets. The total cemented carbide production in was aro tons and increased f tons () to alm tons inparticularly due to the entry of China on to the market. From year and to date the cemented carbide production in China raised from tons Cemented carbide book to 20, tons () ().
Cemented carbide grades that can withstand these high temperatures are the most successful. Carbide formed into different configurations are the most popular, and they are called indexable inserts.
Indexable inserts are used for various shapes of holders and selected according to. Back to book. chapter 5. 31 Pages.

Cemented Carbide Market: Introduction. Cemented carbide consists of fine particles of carbide cement and metal composites. It is a hard material, which is primarily used as a cutting tool material. Cemented carbide is available in the form of tungsten carbide (WC), titanium carbide (TiC), and tantalum carbide (TaC) as aggregate.
This paper presents a study of grinding cemented carbide DKUF (91 % WC and 9 % Co), a material used to produce cutting tools with solid cutting edges. The aim is to establish the manufacturing. Cemented carbide was first invented by Bavarians to make wire drawing dies.
In other words, wire drawing die is the direct incentive of the appearance of cemented carbide. In s, cemented carbide industry grew up in China. Since then, cemented carbide drawing die has been gradually gaining popularity in China.
The cemented tungsten carbide composite was discovered during the First World War () as a substitute for diamond in wire drawing applications.
Very soon its applications were found in cutting tools, wear-resistant parts, and various other machine parts. Several other carbide systems and their combinations have been studied in order to.

With its 80 years of track record and an abundance of grades that meet diverse applications, the cemented carbide has gained.
Cemented carbide is currently used for various precise molds and wear resistant parts. However, the machining of cemented carbide still is a difficult challenge due to its superior mechanical properties. In this paper, an experimental study was conducted on direct micro milling of cemented carbide with a polycrystalline diamond (PCD) micro end mill.
