Abstract
The combined deoxidation of Fe–Ni melts by manganese and aluminum at 1873 K is thermodynamically analyzed. The dependences of oxygen solubility on the manganese and aluminum content are calculated for the Fe–40% Ni melt. The combined deoxidation of the Fe–40% Ni melt by manganese and aluminum is experimentally studied in the range 0.1–0.3% Mn and 0.0005–0.056% Al at 1873 K. The oxygen concentration is found not to depend on the manganese content in the manganese content range under study (0.1–0.3%). The experimental data obtained are in good agreement with the results of thermodynamic analysis, from which it follows that the effect of manganese on the deoxidation ability of aluminum in the Fe–40% Ni melt in the range 0.1–1% Mn can be significant if the aluminum content is lower than 0.0005%.
从热力学角度分析了锰和铝在 1873 K 下对铁-镍熔体的联合脱氧作用。计算了 Fe-40% Ni 熔体的氧溶解度与锰和铝含量的关系。实验研究了在 1873 K 下,锰含量为 0.1-0.3% 和铝含量为 0.0005-0.056% 的范围内,锰和铝对 Fe-40% Ni 熔体的联合脱氧作用。所获得的实验数据与热力学分析结果十分吻合,由此可见,在锰含量为 0.1-1% 的范围内,如果铝含量低于 0.0005%,锰对 Fe-40% Ni 熔体中铝的脱氧能力的影响是显著的。
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.
