The alloys were found to consist of three phases: refractory phase, TiNi, and delta-Ni2V3 or NbzNi. 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 Полный текст |
