Abstract
The phase composition of V- or Nb-containing titanium-carbonitride-base cermets with a TiNi binder was investigated, and the content of the alloying metal in the refractory base of the alloys was determined. The alloys were found to consist of three phases: refractory phase, TiNi, and &sgr;-Ni_2V_3 or Nb_zNi. The solubility of V in titanium carbonitride is very low, while that of Nb is fairly high and increases with Nb content. The phase composition of the cermets is shown to correlate with the Gibbs energies of formation of the constituent carbides.
