Определены условия снижения загрязненности указанных сталей скоплениями нитридов титана. Для упрощения расчетов создан общедоступный интерактивный сайт. Для расплава 20/20 условия образования TiN рассчитаны также с помощью системы Thermo-Calc. Полученные при этом значения растворимостей TiN значительно превышают результаты указанных выше расчетов, которые согласуются с известными экспериментальными данными. Эти расхождения связаны в основном с уточнением величин коэффициентов активности титана в расплавах на основе железа, которое в системе Thermo-Calc пока не учтено. Даны рекомендации по использованию результатов на практике.</p></abstract><trans-abstract xml:lang="en"><p>Using the new, verified by the authors earlier reference data after additional check of their adequacy thermodynamic conditions of formation of inclusions of TiN in steel melts Cr18Ni12T (18/12) and Cr20Ni20T (20/20) types were calculated. Conditions of decrease in impurity specified melts by congestions of TiN were defined. For simplification of calculations the public interactive site is created. For the melt of 20/20 conditions of formation of TiN were calculated also by means of known Thermo-Calc system. The values of TiN solubilities received thus considerably exceed results of the calculations stated above which are compatible with known experimental data. These divergences are connected generally with verification of titan activity coefficients in melts on the iron base which in Thermo-Calc system are not considered yet. The authors have given the recommendations about the use of the research results on practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>TiN</kwd><kwd>азот</kwd><kwd>титан</kwd><kwd>нитрид титана</kwd><kwd>растворимость нитрида</kwd><kwd>коэффициент активности</kwd><kwd>параметр взаимодействия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>TiN. nitrogen</kwd><kwd>titan</kwd><kwd>titan nitride</kwd><kwd>solubility of nitride</kwd><kwd>activity coefficient</kwd><kwd>interaction parameter</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">Самсонова М.А., Костина М.В., Блинов В.М.
