Впервые определены константы равновесия реакций взаимодействия титана и кислорода, коэффициенты активности при бесконечном разбавлении и параметры взаимодействия в расплавах различного состава при 1873 К. По мере роста содержания кобальта в расплаве константы равновесия реакций взаимодействия титана и кислорода уменьшаются от железа ((lgK(FeO·TiO2) = -7,194; lgK(TiO2) = -6,125; lgK (Ti3O5) = -16,793; lgK (Ti2O3) = -10.224) к кобальту (lgK (CoO· TiO2) = -8.580; lgK (TiO2) = -7.625; lgK (Ti3O5) = -20.073; lgK (Ti2O3) = -12.005). Определены значения содержаний титана в точках равновесия между оксидными фазами (Fe. Со)О· TiO2. TiO2, Ti3O5 и Ti2O3. Содержание титана в точке равновесия (Fe. Со)О · TiO2 ↔TiO2 уменьшается от 1,0· 10-4 % Тi в железе до 1,9-10-6 % Тi в кобальте. Содержание титана в точке равновесия TiO2 ↔ Ti3O5  повышается от 0.0011 % Тi в железе до 0.0095 % Тi в кобальте. Содержание титана в точке равновесия Ti3O5 ↔ Ti2O3, повышается от 0.181 % Тi в железе до 1.570 % Тi в кобальте. Рассчитаны зависимости растворимости кислорода в изученных расплавах от содержания кобальта и титана. Показано, что раскислительная способность титана при увеличении содержания кобальта до 20 % снижается. а затем возрастает по мере увеличения содержания кобальта в расплаве. В железе, сплавах Fe - 20 % Со и Fe - 40 % Со раскислительная способность титана практически одинаковая. Кривые растворимости кислорода в железокобальтовых расплавах, содержащих титан, проходят через минимум, положение которого смещается в сторону более низких содержаний титана по мере увеличения содержания кобальта в расплаве. Дальнейшие присадки титана приводят к возрастанию концентрации кислорода в расплаве. При этом, чем выше содержание кобальта в расплаве, тем резче возрастает концентрация кислорода после минимума по мере добавления титана в расплав.</p></abstract><trans-abstract xml:lang="en"><p>Thermodynamic analysis of oxygen solutions in titanium- containing Fe-Co melts was carried out. The equilibrium constants of interaction of titanium and oxygen dissolved in the Fe-Co melts, the activity coefficients of titanium and oxygen at infinite dilution, and the interaction parameters characterizing these solutions for melts of different composition at 1873 К were determined for the first time. As the cobalt content in the melt grows the equilibrium constants of interaction of titanium and oxygen are decreased from iron (lgK(FeO·TiO2) = -7,194; lgK(TiO2) = -6,125; lgK (Ti3O5) = -16,793; lgK (Ti2O3) = -10.224) to cobalt (lgK (CoO· TiO2) = -8.580; lgK (TiO2) = -7.625; lgK (Ti3O5) = -20.073; lgK (Ti2O3) = -12.005). Titanium contents in equilibrium points of oxide phases (Fe, Со) О· TiO2. TiO2, Ti3O5 and Ti2O3., were determined. The titanium content in equilibrium point (Fe. Со)О · TiO2 ↔TiO2 decreases from 1,0· 10-4 % Тi в in the iron to 1,9-10-6 % Ti in cobalt. The titanium content in equilibrium point TiO2 ↔ Ti3O5 increases from 0.0011 % Ti in the iron to 0.0095 % Ti in cobalt. The titanium content in equilibrium point Ti3O5 ↔ Ti2O3, increases from 0.181 % Ti in the iron to 1.570 % Ti in cobalt. The dependences of the oxygen solubility on the contents of cobalt and titanium in the studied melts were calculated. With increasing cobalt content in melt to 20 %, the deoxidation ability of titanium decreases and then rises with the further addition of cobalt. In iron. Fe-20 % Co and Fe-40 % Co alloys deoxidation ability of titanium is practically the same. The curves of the oxygen solubility in titanium-containing iron-cobalt melts pass through a minimum, which shifts toward lower titanium contents with increasing cobalt content of the melt. Further titanium additions leads to an increase in the oxygen concentration in the melt so that with the higher cobalt content in the melt, the increase in the oxygen content after the minimum is steeper as titanium is added to the melt.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>расплавы Fe-Co</kwd><kwd>титан</kwd><kwd>кислород</kwd><kwd>оксидные фазы</kwd><kwd>термодинамический анализ</kwd><kwd>параметры взаимодействия</kwd><kwd>растворимость кислорода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Fe-Co melts</kwd><kwd>titanium</kwd><kwd>oxygen</kwd><kwd>oxides phases</kwd><kwd>thermodynamic analysis</kwd><kwd>interaction parameters</kwd><kwd>oxygen solubility</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">Сергеев В.В., Булыгина Т.И.
