摘要
The present invention relates to a method of making a WC-Co-based cemented carbide with a fine WC-grain size. The cemented carbide is produced from well deagglomerated or easy to deagglomerate WC powder with round morphology, a Co powder also well deagglomerated or easy to deagglomerate and with a grain size equal to or smaller than the WC grain size and grain growth inhibitors. According to the invention the metal part of the grain growth inhibitors is added as part of the binder phase i.e. is included in the Co powder and alloyed therewith.
