Abstract
Multiple elements have been shown to enhance the oxidation resistance of iron aluminides. In this context, the influence of copper on the FeAl oxidation resistance was investigated. The findings demonstrated that the oxidation resistance of this kind of iron aluminide is greatly increased when the optimal quantity of copper is used. Samples containing 2 %, 7 %, and 12 % copper (depending on the amount of aluminum in each sample) were used to assess how different copper concentrations impact the oxidation behavior of FeAl. Compacted powder samples with equal molar ratios of iron and aluminum and the above-mentioned amounts of copper in each sample, after synthesis at 950°C, were oxidized at 600°C, 700°C, and 800°C for 20, 40, 60, 80, and 100 hours. It was observed that at all tested temperatures, samples with 2 and 7% copper showed less weight gain than the free copper sample. Nevertheless, a higher rate of oxidation was the outcome of raising the copper content to 12%. It's important to note that the samples with 7% copper outperformed the samples with 2% copper in terms of oxidation resistance. Furthermore, a detailed analysis of the resulting compositions and microstructures was conducted.
