  • Method of producing a sintered carbonitride alloy for extremely fine machining when turning with high cutting rates
    Patent number: 5552108
    Abstract: 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 composition0.86.ltoreq.X.sub.IV .ltoreq.0.990.74.ltoreq.X.sub.C .ltoreq.0.83where X.sub.IV is the molar ratio of the group IV elements of the alloy and X.sub.C is the molar ratio of carbon.
