В процессе термической обработки отливок происходило перераспределение элементов между фазами чугуна. Максимальная концентрация хрома в основе после нормализации составила 19,7% при 1,09% С, 3,1% Mn, 25,57% Cr и 0,19% Ni, а минимальная 2,4% при 3,91% С, 0,6% Mn, 11,43% Cr и 0,19% Ni. Максимальное количество хрома в карбидах 78,4% наблюдали в чугуне, содержащем 1,09% С, 5,4% Mn, 3,01% Ni и 25,57% Cr, а минимальное 43,5% при 3,59% С, 5,4% Mn, 3,01% Ni и 11,43% Cr. Полученные зависимости позволяют прогнозировать содержание хрома в металлической основе и могут использоваться при разработке новых составов износостойких чугунов, а также при выборе режимов термической обработки.</p></abstract><trans-abstract xml:lang="en"><p>The dependences of the influence of the chemical composition of cast iron in the Fe-Cr-Mn-Ni system on the chromium cotent in the metal base (Cr1050о) and carbides (Cr1050Cr) after normalization from 1050 °C with aging for 4.5 hours were established. During the heat treatment of the castings, a redistribution of the elements between the phases of the cast iron occurred. The maximum chromium concentration in the base after normalization was 19.7% at 1.09% C, 3.1% Mn, 25.5% Cr and 0.19% Ni, and the minimum 2.4% at 3.91% C, 0.6% Mn, 11.43% Cr and 0.19% Ni. The maximum amount of chromium in carbides 78.4% was observed in cast iron containing 1.09% C, 5.4% Mn, 3.01% Ni and 25.57% Cr, and the minimum 43.5% at 3.59% C, 5.4% Mn, 3.01% N and11.43% Cr. The obtained dependencies allow predicting the chromium content in the metallic base and can be used during the elaboration of new compositions for wear-resistant cast iron, as well as at choice of heat treatment regimes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>чугун</kwd><kwd>нормализация</kwd><kwd>хром</kwd><kwd>распределение</kwd><kwd>металлическая основа</kwd><kwd>карбиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cast iron</kwd><kwd>normalization</kwd><kwd>chromium</kwd><kwd>distribution</kwd><kwd>metallic base</kwd><kwd>carbides</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">Цыпин И.
