Effect of carbide powder characteristics on the PVT behavior of powder injection molding compounds

Popis výsledku v původním jazyce

Effect of powder concentration and particle size distribution of highly filled cemented carbide compounds on their pressure-volume-temperature (PVT) characteristics and thermal properties was investigated. PVT data of compounds containing up to 50. vol.%of powder evaluated on a high-pressure mercury dilatometer reveals that the pressure influences both detected phase transitions, but it causes a different effect on the melting and crystallization of the material only for the higher transition (corresponding to binder components with melting temperatures 100 and 107 °C). The discrepancies in specific volumes at an applied pressure diminish with increasing powder content, whereas melting temperatures - derived from differential scanning calorimetry - remain unaffected. Volumetric thermal expansion coefficient and compressibility are linearly and exponentially, respectively, dependent on pressure. Further, the variance in the particle size distributions of carbide compounds resulted in s
