A cemented carbide material having (i) between 75-95 weight percent tungsten carbide, (ii) a cobalt/iron/nickel binder phase with nanoparticles having a mean grain size no greater than 10nm and (iii) the volume percentage of tungsten carbide grains have a grain size no greater than 1µm and less than 4% volume. The nanoparticles include material according to the formula CoxWyCz, where x is a value in the range from 1 to 7, y is a value in the range from 1 to 10 and z is a value in the range from 0 to 4. A method for producing the cemented carbide material is also disclosed, as shown by the figure below. |
