Definition

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 2012). The proportion of carbide phase is generally between 70 % and 97 % of the total weight of the composite and its grain size averages between 0.4 and 10 μm. In cemented carbides, these hard particles are mainly tungsten carbides (WC) compared to cermets (TiC, TaC, NiC) or ceramics where metal oxides or nitrites are used.

Theory and Application

Cemented carbide is one of the most successful composite engineered materials. Its unique combination of strength, hardness, and toughness satisfies the most demanding applications.

History

The development of this highly optimized cutting material is strongly connected to the history of the industrial manufacturing. First important invention which had very practical impact on the cutting technology was...
