متن کاملCemented Carbides – a Success Story
After WW2, a huge market opened in the growing economies and cemented carbides contributed as tool materials and construction parts to their industrial development. Today, cemented carbides are the workhorses in all areas of the manufacturing industries: no factory without cemented carbide tools; no production of glass bottles, aluminium cans or plastic tubes which has not benefited from these ...
متن کاملCharacterization of metal powder suspension to improve the functionality of cemented carbides
Cemented carbide is produced by sintering a mixture of metal carbides and binder. Both materials are formed into granulated powders via suspension with the object of a uniform product and an easy handling. And the granule was sintered to produce final products. In addition to excellent toughness and wear, accurate and minute figuration is required for commercial products. The method to produce ...
متن کاملEffect of WC/Co coherency phase boundaries on Fracture toughness of the nanocrystalline cemented carbides
The effect of coherency WC/Co phase boundaries on the fracture toughness of the nanocrystalline WC-Co cemented carbides is studied by MD simulation method. The simulation results show that the nanocrystalline WC-Co cemented carbides with coherency WC/Co phase boundaries has higher fracture toughness than that without coherency WC/Co phase boundaries. Moreover, the mechanism of why coherency WC/...
متن کاملFocused Ion Beam tomography of WC-Co cemented carbides
The microstructure of three different grades of WC-Co cemented carbides has been reconstructed in three dimensions after sequential images obtained by focused ion beam. The three-dimensional microstructual parameters are compared against the well-know two-dimensional parameters of grain size, phase percentages and mean free path. Results show good agreement with the exception of individual grai...
