Для изучения возможности легирования моноалюминида железа хромом в процессе синтеза использовали реакционные смеси, содержащие в качестве источника хрома порошки оксида хрома или сплава ПХ-30. Порошки получали методом механоактивируемого самораспространяющегося высокотемпературного синтеза (МАСВС). Испытания на циклическое окисление проводили при температуре 700–1000 °С в атмосфере воздуха в течении 2 ч. В случае использования для легирования интерметаллида сплава ПХ-30 полученный порошок проявляет больший прирост массы в отличие от порошка, синтезированного из реакционной смеси, содержащей оксид хрома, в котором хром не только легировал алюминид, но и присутствовал в свободном состоянии.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>The results of studies of effect of structural state of chromium in the composite SHS-powder FeAl(Cr)/Al2O3 on its resistance to oxidation are presented. To study the possibility of alloying of mono-aluminide iron with chromium, the synthesis reaction mixture containing a source of chromium as chromium oxide powders or alloy PХ-30 were used. Powders were prepared by self-propagating mechanoactivated high-temperature synthesis (MASHS). Cyclic oxidation tests were conducted at a temperature of 700–1000°C in an air atmosphere for 2 hours. In the case of alloying the intermetallic alloy PX-30, the resultant powder exhibits a greater weight gain in contrast to powders prepared from a reaction mixture comprising a chromium oxide in which chromium is not only alloyed aluminide but is present in a free state.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминид железа</kwd><kwd>легированный хромом</kwd><kwd>композиционный порошок</kwd><kwd>реакционная смесь</kwd><kwd>механоактивируемый самораспространяющийся высокотемпературный синтез (МАСВС)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminide iron alloyed chromium</kwd><kwd>composite powder</kwd><kwd>reaction mixture</kwd><kwd>mechanoactivated high-temperature synthesis (MASHS)</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">Stoloff, N.
