Abstract
The influence of alloying titanium carbonitride TiC0.5N0.5 by transition metals of Groups IV–VI on the mechanism of contact interaction with the nickel melt is studied. It is established that alloying metals exert a strongly destabilizing influence on titanium carbonitride TiC0.5N0.5, simultaneously increasing both its dissolution rate in nickel and the degree of process incongruence (the preferential transition of alloying metal and carbon into the melt). The influence of alloying on the phase stability of titanium carbonitride TiC0.5N0.5 in contact with a nickel melt manifests itself in its dehomogenization or phase separation. The destabilizing effect of alloying additives enhances in a series MeIV–MeV–MeVI parallel with a decrease in their nitrogen affinity.
