Synthesis of A Pure Feal With A Density Greater Than 95% of Theoretical Density By Optimizing Effective Factors

In this study, the feal with a density greater than 95% of the theoretical density was synthesized by optimizing the compacting pressure, the particle size of iron and aluminum, and the pre-heating temperature. 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.
