“…However, it increased from less than 90° to around 140° when carbon content increased in the melt [39]. In the study performed by Rubio et al [42], the Fe-14.1Si alloy was found to be much lower, reaching 38° at 1550 °C, which had a similar angle with our experimental result.…”

Fe-26.38Si-9.35B eutectic alloy is proposed as a phase change material (PCM) as it exhibits high latent heat, high thermal conductivity, moderate melting point, and low cost. For successful implementation of it in the latent heat thermal energy storage (LHTES) systems, we investigate the use of graphite as a refractory material that withstands long-term melting/solidification in contact with the Fe-26.38Si-9.35B alloy. The PCM has been thermally cycled up to 1–4 times below and above its melting point at the temperature interval of 20 °C or 100 °C. It is observed that this eutectic alloy shows good thermal stability over a small temperature range of 1057–1257 °C. Some SiC and B4C solid precipitation will be formed at the top of the alloy. However, it does not seem to increase with time. The graphite crucible as a refractory material will produce a protective layer of SiC and B4C that will hinder the interaction between the PCM and the crucible. The small volume change during solidification will not break the graphite crucible during cycling. The chemical wear or dissolution of the crucible is negligible. It demonstrates the viability of Fe-26.38Si-9.35B alloy as a heat storage material in this type of container.

“…The treatments of metallurgical modification optimize the microstructure of cast irons. This is generally achieved by increasing the number of nuclei [1][2][3][4]. It is the silicon derived from SiC that has a modifying effect, protecting the alloy from excessive crystallization of cementite (Fe 3 C), which limits the crystallization of graphite, increasing the hardness and brittleness of cast irons-usually locally in areas with high cooling rate.…”

The paper discusses a potential composite produced using the casting method, where the matrix is gray cast iron with flake graphite. The reinforcement is provided by granular carborundum (β-SiC). The article presents model studies aimed at identifying the phenomena at the contact boundary resulting from the interaction of the liquid matrix with solid reinforcement particles. The scope of the research included, primarily, the metallographic analysis of the microstructure of the resulting composite, carried out by using light (LOM) and scanning electron (SEM) microscopy with energy dispersive X-ray spectroscopy (EDS) analysis. The occurrence of metallic phases in the boundary zone was indicated, the contents and morphology of which can be optimized in order to achieve favorable functional properties, mainly the tribological properties of the composite. In addition, the results obtained confirm the possibility of producing similar composites based on selected iron alloys.

“…Furthermore, analysis of the literature shows that silicon carbide impacts the cast iron microstructure. siC was found to be a source of a large amount of nucleus crystallization [12][13][14]. the durability of those nuclei is significantly higher than that of Fesi, since silicon carbide dissolves considerably slower.…”

Various aspects of application of silicon carbide in the process of cast iron Melting the article discusses benefits associated with the use of silicon carbide in the process of melting gray cast iron and ductile cast iron in induction electric furnaces. it presents the analysis of the impact of various charge materials and the addition of a variable amount of siC and Fesi to the fixed charge when melting cast iron of grades GJs 400-15 and GJs 500-7 on mechanical properties and microstructure. Moreover, the article includes an analysis of the efficiency of carburization and the increase in the content of silicon during the application of siC. the article also presents the results of the study of primary modification using silicon carbide at the minimum temperature of temin eutectic and tsol solidus. Based on analysis of the literature, conducted research, and calculations, it was found that the addition of silicon carbide has a beneficial impact on the properties of melted cast iron. the addition of siC in the charge increases the content of C and si without increasing the amount of contaminations. the addition of siC at reduced pig iron presence in the charge decreases production costs, while the use of siC as an inoculant increases both temin and tsol, which is beneficial from the point of view of cast iron nucleation.
