- 摘要：
- Embodiments relate to methods of manufacturing polycrystalline diamond compacts ("PDCs"). In an embodiment, a method of fabricating a PDC includes positioning a plurality of diamond particles adjacent to a cemented carbide material. The cemented carbide material includes one or more types of tungsten-containing eta phases. The method further includes subjecting the plurality of diamond particles and the cemented carbide material to a high-pressure/high-temperature process effective to sinter the plurality of diamond particles so that a polycrystalline diamond table is formed without tungsten carbide grains of the cemented carbide material exhibiting abnormal grain growth that project into the polycrystalline diamond table.
