    摘要： A TiC-based cermet body includes TiC and WC so that the atomic ratio Ti/W is between 2 to 5, and cobalt as the binder phase is present in an amount of between 5 to 25 vol %. Further, the cermet body has at least one element from group V of the periodic table, Mx, so that the atomic ratio Ti/Mx is between 4 to 20 and the atomic ratio W/Mx is between 1 to 6. The cermet body also has Cr in an amount such that the atomic Cr/Co ratio is from 0.025 to 0.14. The cermet body includes both undissolved TiC cores with a rim of (Ti,W,Mx)C alloy as well as (Ti,W,Mx)C grains which have been formed during sintering.

    摘要： The present invention relates to a sintered body of titanium-based carbonitride alloy comprising hard constituents containing at least tungsten in addition to titanium in a binder phase based on cobalt. There are four distinctly different microstructural components, namely: A) cores which are remnants of and have a metal composition determined by the raw material powder; B) tungsten-rich cores formed during the sintering; C) outer rims with intermediate tungsten content formed during the sintering; and D) a binder phase of a solid solution of at least titanium and tungsten in cobalt. Toughness and wear resistance are varied by adding WC, (Ti,W)C, and/or (Ti,W)(C,N) in varying amounts as raw materials.

The body has a binder phase enriched surface zone with a higher binder phase content than in the inner portion of the body in combination with an enrichment of simple hard constituents, i.e., the share of grains with core-rim structure is lower in the surface zone than in the inner of the body. A method of manufacturing the sintered carbonitride alloy is also provided which comprises forming a powder mixture containing binder phase containing Co and/or Ni and hard constituents of carbides and nitrides with titanium as a main component, the mixture having composition which is substoichiometric regarding an interstitial balance and sintering the mixture to completely transform the substoichiometric phases to stoichiometric by heating a) in vacuum to 1100-1200 C., b) in vacuum at about 1200 C. for about 30 minutes, c) in deoxidizing H.sub.2 -atmosphere for 15-30 minutes at about 1200 C., d) in N.sub.2 -atmosphere during heating to sintering temperature 1400-1600 C., and e) cooling to room temperature in vacuum or inert gas.
