Abstract (en)

[origin: WO9211393A1] According to the invention there now is provided a method of producing a sintered titanium based carbonitride alloy with 3-25 weight % binder phase with extremely good properties at extreme fine machining when turning with high cutting rates. The method relates to the use of a raw material comprising a complex cubic carbonitride containing the main part of the metals from groups IV and V of the periodic system and carbon and nitrogen to be found in the finished alloy whereby said alloy has the composition 0.86 </= XIV </= 0.99, 0.74 </= XC </= 0.83 where XIV is the molar ratio of the group IV elements of the alloy and XC is the molar ratio of carbon.
