Abstract

The effects of alloying elements on the mechanical, microstructural, and corrosion properties of Aluminum have been investigated. This investigation was done by fabricating alloys of Aluminum and Magnesium, with magnesium concentrations of 0.0, 0.1, 0.4, 0.8, 1.2, 1.5, and 1.8 weight percent. Subsequently, the mechanical properties of the samples were tested. Optical microstructural examinations were carried out on each of the samples, and the corrosion properties in a 0.2M H2SO4 solution were determined using the coupon testing method. The results obtained show that Magnesium does not just affect the mechanical, microstructural, and corrosion properties of Aluminum, but these properties are also dependent on the relative content of Aluminum and Magnesium. It was observed that 70 (RHB) was the maximum hardness obtained, and it occurs at 0.8 wt% Mg, after which the hardness becomes negatively affected. Magnesium addition was also found to increases the corrosion rate of (1XXX) aluminum in 0.2M H2SO4. It was also observed from the micrographs of the alloys that there was a uniform dispersion of Magnesium in the matrix of Aluminum
