摘要

摘要/ abstract摘要：对1873 K时硅对Ni-Co-Cr熔体氧溶解度的影响进行了热力学分析。Ni-Co-Cr熔体中少量的硅对氧浓度的影响较弱，氧浓度由铬含量决定。硅含量越高，铬、硅与氧的相互作用机制发生改变后，氧浓度降低，硅决定熔体中氧的溶解度。然而，当硅含量高时，Ni-Co - cr熔体中硅的氧化能力明显低于Ni-Co熔体。

Effect of Silicon on the Oxygen Solubility in Ni–Co–Cr Melts

Abstract—A thermodynamic analysis of the effect of silicon on the oxygen solubility in Ni–Co–Cr melts at 1873 K is performed. Small amounts of silicon present in the Ni–Co–Cr melts weakly affect the oxygen concentration, which is determined by the chromium content. The oxygen concentration decreases at a higher silicon content, after changing the interaction mechanism of chromium and silicon with oxygen when silicon determines the oxygen solubility in the melt. However, at high silicon contents, the oxidation ability of silicon in the Ni–Co–Cr melts is substantially lower than that in the Ni–Co melts.

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.
