Continuous Measurement of Sintering Shrinkage of Tungsten Compacted Powders
Hiroshi Ito, Hiroshi Yamamoto, Kei Tokumoto
Key words Tungsten, powder, compacts, sinter, direct current heating, shrinkage, continuous measurement, electrical resistivity, voltage, electrical current, microstructure


To analyze the sintering process of tungsten compacted powders, shrinkage data had been calculated from the difference in shape between green compact and its sintered body, while electrical currents and voltage for direct current heating were continuously measured in the sintering process.
In this study, continuous measurement of shrinkage in the sintering process has become available. These data have opened the way to more detailed analysis of the sintering process.
