Определены значение константы равновесия реакции взаимодействия титана и кислорода, растворенных в расплаве Fe  –  40 % Ni ( = –15,17), энергия Гиббса этой реакции ( = 543 360 Дж/моль) и параметры взаимодействия, характеризующие эти растворы ( = –1,420;  = –0,472; = 0,116). В широком диапазоне составов сплавов системы Fe – Ni рассчитаны при 1873 К константы равновесия реакции взаимодействия титана и кислорода, растворенных в расплаве, энергия Гиббса реакции взаимодействия титана и кислорода и параметры взаимодействия, характеризующие эти растворы. Определена растворимость кислорода в расплавах системы Fe – Ni различного состава, содержащих титан, при 1873 К. Раскислительная способность титана при увеличении содержания никеля до 40 % снижается, а затем резко возрастает по мере увеличения содержания никеля в расплаве. Это можно объяснить тем, что по мере возрастания содержания никеля, с одной стороны, существенно ослабевают силы связей атомов кислорода в расплаве ( = 0,0103; = 0,337), с другой – значительно возрастают силы связей атомов титана с основой ( = 0,0083; = 0,000083). Кривые растворимости кислорода в железоникелевых расплавах проходят через минимум, положение которого смещается в сторону более низких содержаний титана по мере увеличения содержания никеля. </p></abstract><trans-abstract xml:lang="en"><p>The oxygen solubility in the titanium-containing iron-nickel melts has been experimentally studied at 1873 K using the Fe  –  40  %  Ni alloy as an example. The equilibrium constant of interaction of titanium and oxygen dissolved in the Fe  –  40  %  Ni melt (   = –15,17), the Gibbs energy of this reaction (  =  543  360  J/mol), and the interaction parameters characterizing these solutions (  = –1,420;    =  –0,472;   =  0,116) were determined. The equilibrium constant of interaction of titanium and oxygen dissolved in the melt, the Gibbs energy of reaction of titanium and oxygen interaction, and the interaction parameters characterizing these solutions were calculated in a wide range of Fe – Ni alloys compositions at 1873 K. Oxygen solubility in the various compositions titanium-containing Fe – Ni melts was determined at 1873 K. When the nickel content rises to 40 %, the deoxidation ability of titanium decreases but then it sharply rises with increasing nickel content in melt. This can be explained by the fact that although the bond strength of titanium in nickel is considerably stronger in comparison with iron ( = 0,0083; = 0,000083), but the bond strength of oxygen in nickel is appreciably weaker that in iron (  = 0,0103; = 0,337). The oxygen solubility curves in Fe – Ni melts pass through a minimum whose position shifts to the lower titanium concentrations with an increase in the nickel content.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железоникелевые расплавы</kwd><kwd>растворимость кислорода</kwd><kwd>титан</kwd><kwd>экспериментальное исследование</kwd><kwd>термодинамический анализ</kwd><kwd>параметры взаимодействия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>iron-nickel melts</kwd><kwd>oxygen solubility</kwd><kwd>titanium</kwd><kwd>experimental study</kwd><kwd>thermodynamic analysis</kwd><kwd>interaction parameters</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Steelmaking Data Soucebook.
