Исследовано влияние соотношения концентраций Ti/B и скорости охлаждения на микроструктуру, фазовый состав и твердость стали с повышенным содержанием бора (более 2 %). Показано, что микроструктура стали состоит из частиц боридов (Fe, Cr)2B и TiB2 , равномерно распределенных в ферритной основе. Увеличение скорости охлаждения приводит к уменьшению размеров TiB2 с 20 до 2 мкм, образованию более дисперсной эвтектики феррит + (Fe, Cr)2B и, как следствие, повышению твердости.</p></abstract><trans-abstract xml:lang="en"><p>Steels with high boron content are the most used material for the compact storage racks for used nuclear fuel. The inﬂuence of the concentration ratio of Ti/B and the cooling rate on the microstructure and hardness of the steel with a high content of boron was investigated. It is shown that the microstructure of steel is composed of particles of (Fe, Cr)2B and TiB2 , uniformly distributed in the ferrite matrix. Increasing the cooling rate leads to a decrease TiB2 sizes from 20 to 2 micrometers and to disperse of the eutectic ferrite + (Fe, Cr)2B and, consequently , increased the hardness.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сталь</kwd><kwd>бориды</kwd><kwd>микроструктура</kwd><kwd>твердость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steel</kwd><kwd>borides</kwd><kwd>microstructure</kwd><kwd>hardness</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа  выполнена при финансовой поддержке Министерства  образования  и  науки  Российской  Федерации  по  реализации  комплексного проекта по созданию высокотехнологичного производства  по теме: «Создание современного производства стеллажей хранения</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">HeL., Liu Y., Li J., Li B. // Materials and Design. 2012.
