Patent ID: 8211358

Claim:
A method of making a cemented carbide, the cemented carbide including WC and a binder phase based on Co, Ni or Fe, and a gamma phase, the method comprising: wet milling powders forming hard constituents and binder phase; drying the wet milled powders; and pressing and sintering the dried milled powders to form a body having a desired shape and a desired dimension, wherein powders forming gamma phase are added as a cubic mixed carbide (Me,W)C alloyed with an amount of WC, the amount of WC given by mol fraction of WC, x WC , wherein Me is one or more of Ti, Ta, Nb, Zr, Hf and V, wherein a ratio, f WC , between x WC and an equilibrium gamma phase WC content at a sintering temperature expressed as mol fraction WC, xe WC , is given by: f WC =x WC /xe WC wherein f WC is 0.6 to ≦1.0.
