Установлено, что модифицирование сплава АК7ч приводит к равномерному распределению эвтектики (α-Al + β-Si), структурных составляющих, уменьшению кристаллов кремния в среднем в 1,5–2,0 раза, измельчению и изменению формы Fe-содержащих фаз. Показано, что для всех модифицированных образцов характерно увеличение относительного удлинения в 2 и более раз, при этом временное сопротивление разрыву, твердость и плотность отливок для всех образцов различны и носят неоднозначный характер.</p></abstract><trans-abstract xml:lang="en"><p>The results of experimental studies of the AK7ch Al–Si alloy before and after modifying with compositions—(i) the K2ZrF6 industrial modifier, (ii) modifying mixture based on oxides of refractory metals and cryolite, and (iii) the «Arsal 2120» foreign flux – are presented.It is established that modification of the AK7ch alloy leads to the uniform distribution of eutectics (α-Al + β-Si), structural components, decrease in silicon crystals by a factor of 1,5–2,0 on average, refining, and variation in shape of Fe-containing phases. It is shown that an increase in relative elongation by a factor of 2 and more is characteristics for all modified samples, and the tensile strength, hardness, and density of casts for all the samples are different and has an ambiguous character.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сплав АК7ч</kwd><kwd>модифицирование</kwd><kwd>железосодержащие фазы</kwd><kwd>механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>AK7ch alloy</kwd><kwd>modification</kwd><kwd>iron-containing phases</kwd><kwd>mechanical properties</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">Stroganov G.V., Rotenberg V.A., Gershman G.B.
