To do so, the products of the samples which were examined by the change of the particle size of 10µm and 50µm, the pre-heating temperatures of 25°C, 287°C and 550°C and the compacting pressures of 400MPa, 500MPa, and 600MPa, were studied. According to the appearance, composition, density, hardness, and oxidation resistance, the optimum sample was determined. The optimal FeAl had a density of more than 95% of the theoretical density, which was prepared using the particle size of 10/10 of iron and aluminum, the pre-heating temperature of 550°C, and the compacting pressure of 500 MPa. The duration of the pre-heating and the synthesis was also 5 and 3h, respectively. It was found that without pre-heating, there is no possibility of producing a compact and dense product. It was also found that the particle size of the iron is more effective than the particle size of aluminum to achieve the qualified FeAl product.Read More
