Abrégé
(EN)
The present invention relates to a WC-Co cemented carbide alloy. By adding an extremely small amount of Ti, V, Zr, Ta or Nb or a combination of these, a grain refined cemented carbide structure with less abnormal WC-grains has been obtained.
(FR)
La présente invention concerne un alliage de carbure cémenté WC-Co. En ajoutant une quantité extrêmement faible de Ti, V, Zr, Ta ou Nb ou une combinaison de ceux-ci, une structure de carbure cémenté affinée comportant moins de grains de WC anormaux a été obtenue.
