Эта теория полностью аналогична теории для жидких растворов азота в сплавах системы Fe ‒Cr и Fe‒Mn, предложенных авторами ранее в 2019 и  2020  г. Теория основана на решеточной модели растворов Ni‒Cr. Предполагается модельная решетка типа ГЦК. В узлах этой решетки располагаются атомы никеля и хрома. Атомы азота располагаются в  октаэдрических междоузлиях. Атом азота взаимодействует лишь с  атомами металлов, находящимися в соседних с этим атомом узлами решетки. Это взаимодействие парное. Предполагается, что энергия этого взаимодействия не зависит ни от состава сплава, ни от температуры. Принимается, что жидкие растворы в системе Ni‒Cr являются совершенными. В рамках предложенной теории получено выражение для вагнеровского параметра взаимодействия азота с  хромом в  жидких сплавах на основе никеля. Правая часть соответствующей формулы представляет собой функцию отношения констант закона Сивертса для растворимости азота в жидких хроме и никеле. Значение этих констант для температуры 1873  К приняты равными K′(Cr)  =  15,2; K′(Ni)  =  0,0015  % (по массе). При этом получена оценка для вагнеровского параметра взаимодействия в сплавах на основе никеля   =  21,4. Это соответствует значению лангенберговского параметра взаимодействия  =  –0,105, что очень близко к экспериментальным оценкам   =  –0,108 для температуры 1873 К (Суровой и др., 1971 г.) и   =  –0,11 для температуры 1823 К (Стомахин и др., 1965 г.).</p></abstract><trans-abstract xml:lang="en"><p>The authors propose a simple theory of thermodynamic properties of nitrogen solutions in liquid Ni–Cr alloys. This theory is completely analogous to the theory for liquid nitrogen solutions in alloys of the Fe–Cr and Fe –Mn systems proposed previously by the authors in 2019 and 2020. The theory is based on lattice model of the Ni–Cr solutions. The model assumes FCC lattice. In the sites of this lattice are the atoms of Ni and Cr. Nitrogen atoms are located in octahedral interstices. The nitrogen atom interacts only with the metal atoms located in the lattice sites neighboring to it. This interaction is pairwise. It is assumed that the energy of this interaction depends neither on the composition nor on the temperature. It is supposed that the solutions in the Ni–Cr system are perfect. Within the framework of the proposed theory, a relation is obtained that expresses the Wagner interaction coefficient between nitrogen and chromium in liquid nickel-based alloys. The right-hand part of the appropriate formula is a function of ratio of the Sieverts law constants for solubility of nitrogen in liquid chromium and nickel. The values of these constants for the temperature of 1873  K are assumed to be K′(Cr)  =  15,2; K′(Ni)  =  0,0015 wt.  %. An estimate is obtained for the Wagner interaction coefficient in nickel-based alloys   =  21,4. This corresponds to the value of the Langenberg interaction coefficient  =  –0,105, wich is very close to the experimental estimates  =  –0,108 for the temperature of 1873 K (Surovoi et al., 1971) and   =  –0,11 for the temperature of 1823 K (Stomakhin at al., 1965). </p></trans-abstract><kwd-group xml:lang="ru"><kwd>термодинамика</kwd><kwd>растворы</kwd><kwd>азот</kwd><kwd>хром</kwd><kwd>никель</kwd><kwd>коэффициенты активности</kwd><kwd>вагнеровский параметр взаимодействия</kwd><kwd>ланген берговский параметр взаимодействия</kwd><kwd>закон Сивертса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermodynamics</kwd><kwd>solutions</kwd><kwd>nitrogen</kwd><kwd>chromium</kwd><kwd>nickel</kwd><kwd>activity coefficient</kwd><kwd>Wagner interaction coefficient</kwd><kwd>Langenberg interaction coefficient</kwd><kwd>Sieverts law</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">Nicolas-Louis Vauquelin.
