“…Iron aluminides have attracted considerable attention since the 1950s to replace cast iron [1,2], while some limitations have been reported for them [3]. Various approaches have been proposed to add some elements such as Cr, Ta, and Nb [4,5] to improve the oxidation and corrosion resistance of iron aluminides. It is also identi ed that a certain amount of aluminum content in compounds is needed to achieve maximum oxidation resistance [6].…”

Iron aluminides are widely considered the most important materials due to their lightweight, low cost, easy sintering, and resistance to oxidation and sul dation. The presence of silicon in some alloys containing aluminum has had positive effects on their oxidation resistance. Few researchers have addressed the effect of silicon on the oxidation behavior of iron aluminide which is formed using elemental powders of Fe, Al, and Si. Therefore, in this research, the amount of silicon was changed and the effects of Si content on the oxidation behavior of iron aluminide were investigated. To achieve this goal, the elemental powders of Fe and Al (with a molar ratio of 1:1) along with different amounts of Si were pressed and sintered at 950°C. The samples were oxidized in air at temperatures of 600°C, 700°C, and 800°C, consequently. The ndings con rm that silicon up to a certain content can improve the oxidation resistance of iron aluminide. The morphology of the obtained phases is in uenced by the amount of silicon as well.

The present paper reviews and analyses different models that could be used to describe the adsorption equilibrium of pure gases. The adsorption equilibrium of hydrogen, nitrogen and methane is characterised and modelled. Several thermodynamic conceptions have been selected and tested for the calculation of physico-chemical parameters. The model of Dubinin has been selected to estimate the pseudo-saturation vapour pressure. The best results for the molar volume of the adsorbate have been obtained by using Do’s equation. Eight models, namely Langmuir, Freundlich, Sips, Toth, Jovanovic, UNILAN, OBMR and Potential Theory, describing the adsorption equilibrium of pure gases, have been tested and compared with experimental data obtained from the literature at three different temperatures (283 K, 298 K and 313 K). In order to determine the best fit, the correlation coefficient and the standard errors for each parameter have been used to evaluate the data. All the models used in this study, except for Freundlich’s equation in the case of nitrogen or methane adsorption, are in good agreement between experiment and modelling for the adsorption isotherms.

Iron aluminides have been receiving much attention due to their excellent properties such as light weight, high strength, oxidation resistance, and corrosion resistance. These types of materials are made in a variety of methods. Various types of additives such as Si, Cr, Ta, and Nb have been added to iron aluminides to improve their properties. Silicon is one of the most effective additives. There are no comprehensive studies that can prove the nal product of the Fe-Al powder system reactions in the presence of silicon. Therefore, equal molar ratios of Fe and Al powders were mixed with different amounts of Si to investigate the effect of silicon on the reactions of Fe-Al/Si powder system. The obtained samples were heat-treated at 950°C in an argon atmosphere. It has been found that the presence of silicon affects not only the type of iron aluminides and iron silicides produced but also the nal morphology.
