摘要

摘要--本文提出了一种方法，通过形成硅钇低温共晶，在制造碳化硅/二硼化锆基体陶瓷复合材料时降低硅熔体渗透温度。通过热力学计算，我们证实了在硅烷化剂中添加钇的做法，并证明了其优点。我们首次在低于硅熔点的温度下将硅熔体渗入复合材料，从而确保降低碳纤维的降解程度，同时使基体保持高密度和均匀性。

Effect of Yttrium on the Properties of Carbon Fiber-Reinforced ZrB2–SiC Composites

An approach is proposed which makes it possible to lower the silicon melt infiltration temperature in the fabrication of silicon carbide/zirconium diboride matrix ceramic composites via the formation of a silicon–yttrium low-temperature eutectic. Using thermodynamic calculations, we have substantiated the addition of yttrium to a siliciding agent and demonstrated its advantages. Silicon melt infiltration into composites has been carried out for the first time at a temperature below the melting point of silicon, which has ensured a decrease in the degree of carbon fiber degradation, while allowing the matrix to retain high density and uniformity.

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
