Cemented 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 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...

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 کاملHealth hazard of poorly regulated exposure during manufacture of cemented tungsten carbides and cobalt.
Forty two of 125 former workers in a factory in Syracuse, New York, which manufactured hard metal parts from tungsten carbide and cobalt, were studied by chest radiographs, spirometry, and plethysmographically determined lung volumes. The plant was closed in 1982 and the studies were performed in 1983-5. Recorded measurements of carbide dust concentrations were only mildly excessive by modern s...
