Abstract (en)
According to the present invention there is now provided a method of manufacturing a sintered body of titanium based carbonitride alloy comprising hard constituents in 525 % binder phase where the hard constituents contain, in addition to Ti, one or more of the metals Zr, Hf, V, Nb, Ta, Cr, Mo or W and the binder phase is based on cobalt and/or nickel with powder metallurgical methods, i.e., milling, pressing and sintering. If the powder to be compacted has a mean agglomerate size of 40-80 mu m and a span of <1.5 less porosity and lower compaction pressure is obtained.
