Abstract—The chemical and phase compositions, structure and mechanical properties of an alloy based on the NiAl—Cr—Co system (base–2.5Mo–1.5Re–1.5Ta–0.2Ti) obtained by centrifugal SHS casting in a pilot industrial plant have been studied. The results of the study were analyzed in comparison with similar parameters for an alloy of the same composition, but synthesized in a laboratory SHS plant and having a smaller mass of 0.8 ± 0.1 kg as compared to the mass of a large-sized ingot of 4.7 ± 0.1 kg. The large-sized ingot with chemical and phase compositions uniform by volume is reported to have been produced, its metal demonstrating similar kinetics and heat resistance at 1150°C (30 h) at different distances from the center. It was found that the heat resistance of the alloy decreased with ingot mass increasing from 55 ± 3 g/m2 for the laboratory ingot to 19 ± 3 g/m2 for the large ingot. The strength properties of the metal of the large ingot during compression testing were \(\sigma _{{\text{u}}}^{{\text{c}}}\) = 1662 ± 10 MPa, \(\sigma _{{0.2}}^{{\text{c}}}\) = 1531 ± 25 MPa and during tensile testing σu = 293 ± 10 MPa, σ0.2 = 236 ± 5 MPa, which was practically no different from the properties of the laboratory ingot. The mechanical properties of NiA–Cr–Co-based alloys of various alloying systems synthesized by the SHS method with subsequent use of special metallurgy methods are also given.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
