“…If one focuses instead on the Ni/carbide interface, pseudobinary sections indicate eutectics exist in each case. The eutectic temperatures and compositions are 1290 • C at 94 mol% Ni for the Ni-ZrC system, 31 1330 • C at 94.4 mol% Ni for the Ni-HfC system 32 and 1350 • C at 94.5 mol% Ni for the Ni-TaC system. 31 The ZrC material contains free C and thus a Ni/C interface can exist locally along the interlayer/carbide interface; the Ni-C system has a eutectic at 1326 • C and 92 at.% Ni.…”

“…The advantage of using nickel is seen not only in economic feasibility and in the simplification of the use of nickel protective wearresistant and heat-resistant alloy on parts of gas turbine engines. It also consists in the absence of polymorphic transformations in nickelbased alloys; in the probable additional strengthening due to γ′-phase; in the same thermodynamic conditions of two-phase equilibrium of nickel and cobalt with niobium carbide with a melting diagram of the eutectic type [9,10].…”

The melting temperature, microstructure, and phase composition of cast eutectic alloys with niobium carbide, in which the metal base represented by nickel or nickel and cobalt, are studied by methods of physicochemical analysis. The properties of the studied alloys are comparable with the corresponding properties of the industrial eutectic composite based on cobalt with niobium carbide. The melting point of the eutectic (solidus) of nickel-based alloys is above 1300°C and does not differ from the corresponding value for cobalt serial alloy. The structure of alloys has slightly over-eutectic features and is determined by the presence of primary undeveloped niobium carbide dendrites in the eutectic of dispersed eutectic carbide crystals in an alloyed metal base. In the phase composition of the studied alloys, along with a solid solution of alloying elements in Nickel (γ) and niobium carbide (NbC), there are metastable phases enriched in chromium and rhenium. According to the complex of structural properties, cast eutectic alloys of nickel with niobium carbide are promising for use as an alternative to cobalt alloys of the ХТН series.

Статья содержит примеры того, что построение диаграмм фазовых равновесий и исследование строения и свойств эвтектических сплавов на основе металлов Cr, Mo, W, Fe, Ni, Co c карбидами тугоплавких металлов IV-V(A) групп TiC, ZrC, HfC, VC, NbC является основой разработки сплавов для машиностроения. Ключевые слова: диаграмма фазовых равновесий, эвтектика, металл, карбид, сплав. Стаття показує, що дослідження фазових рівноваг, будови та властивостей стопів на основі металів Cr, Mo, W, Fe, Ni, Co з карбідами металів IV-V(A) груп TiC, ZrC, HfC, VC, NbС мають бути основою створення нових стопів для машинобудування.
