Однако, в связи с тем, что получение компактных образцов представляет значительные трудности, в литературе недостаточно данных по их механическим свойствам. В представленной работе разработана технология изготовления никелькремниевых сплавов для проведения механических испытаний, заключающаяся в плавлении сплава под давлением, охлаждении сплава под давлением и снижении давления. Изготовлены шлифы образцов с различным химическим составом, проведено изучение их структуры и микротвердости. В результате изучения установлено, что при увеличении содержания кремния до 30 – 40 % микротвердость никелькремниевых сплавов снижается до 5,5 – 6,0 ГПа, при дальнейшем увеличении содержания кремния микротвердость значительно повышается, что связано с появлением в структуре фаз NiSi2 и Si, имеющих высокие значения микротвердости. </p></abstract><trans-abstract xml:lang="en"><p>Ni – Si alloys are used in the manufacture of heat-resistant coatings. However, due to the fact that the production of compact specimens presents considerable difﬁculties are insufﬁcient data in the literature on their mechanical properties. In this work, the manufacturing techniques Ni – Si alloys for mechanical testing, which consists in melting the alloy under pressure, cooling the alloy under pressure and pressure drop. Polished sample was made of samples with different chemical composition, their structure and microhardness were studied. As a result, the study found that by increasing silicon content up to 30 – 40 % microhardness Ni – Si alloys decreases to 5.5 – 6.0 GPa, with a further increase in the silicon content microhardness increases signiﬁ cantly, due to the presence of the phase structure NiSi2 and Si, that have high microhardness values.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микротвердость</kwd><kwd>микроструктура</kwd><kwd>никелькремниевые сплавы</kwd><kwd>шлифы</kwd><kwd>давление</kwd><kwd>сплавление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microhardness</kwd><kwd>microstructure</kwd><kwd>Ni-Si alloys</kwd><kwd>polished sample</kwd><kwd>pressure</kwd><kwd>melting</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">Jarrige I., Delaunay R., Jonnard P. // Solid state communications. 2005.
