Abstract
Abstract A sintered titanium-based carbonitride alloy contains hard constituents based on, in addition to Ti, W and/or Mo, one or more of the metals Zr, Hf, V, Nb, Ta or Cr in 5-30% binder phase based on Cobalt and/or nickel. The content of tungsten and/or molybdenum, preferably molybdenum in the binder phase is >1.5 times higher than in the rim and >3.5 times higher than in the core of adjacent hard constituent grains. The alloy is produced by a particular method.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
107 words
Sintered titanium-based carbonitride alloy containing hard constituents of a carbide, nitride, carbonitride or combinations thereof of Ti, at least one of W and Mo and at least one metal selected from the group consisting of Zr, Hf, V, Nb, Ta and Cr in 5-30% binder phase of a metal selected from the group consisting of cobalt, nickel and alloys thereof, and said sintered carbonitride alloy containing hard constituent grains with a core-rim structure, the content of molybdenum and/or tungsten in the binder phase being >1.5 times higher than in the rim and >3.5 times higher than in the core of adjacent hard constituent grains with core-rim structure.
Claim 2
Dependent Claim
107 words
Sintered titanium-based carbonitride alloy containing hard constituents of a carbide, nitride, carbonitride or combinations thereof of Ti, at least one of W and Mo and at least one metal selected from the group consisting of Zr, Hf, V, Nb, Ta and Cr in 5-30% binder phase of a metal selected from the group consisting of cobalt, nickel and alloys thereof, and said sintered carbonitride alloy containing hard constituent grains with a core-rim structure, the content of molybdenum and/or tungsten in the binder phase being >1.5 times higher than in the rim and >3.5 times higher than in the core of adjacent hard constituent grains with core-rim structure.
