The Effect of sintering temperature on microstructure and hardness of milled WC- 20 wt.% equiatomic (Fe,Co) cemented carbides
In this study, WC–20 wt.% equiatomic (Fe,Co) powder mixture was milled in a planetary ball mill. The effects of different milling time (15 min, 5h, 10h, and 25 h) and sintering temperatures on the microstructure and mechanical properties of this equi-Fe substituted cermet were investigated. The structural evolution and the crystallite size changes of the powders during milling were monitored by...
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 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 کاملDesign for a Room-Temperature Superconductor
The vision of “room-temperature superconductivity” has appeared intermittently but prominently in the literature since 1964, when W. A. Little and V. L. Ginzburg began working on the problem of high-temperature superconductivity around the same time. Since that time the prospects for room-temperature superconductivity have varied from gloom (around 1980) to glee (the years immediately after the...
