- Abstract
Due to its superior mechanical properties and low weight, metal matrix composite (MMC) materials are widely used in many industries. One of these materials is aluminum matrix composites. Powder metallurgy method being one of the manufacturing methods of aluminum matrix composites is preferred because of the simplicity of the process, low cost and high mechanical properties. In this study, the composite materials were investigated characterization of Al-Mg/Al2O3 composites which added micro-sized Al2O3 particles at different volume ratios (%15-%30) to Al-Mg matrix by using powder metallurgy method. Powders which are available as ready were mixed for 1 day at a speed of 16 rpm to form a homogeneous dispersion. The mixed powders were pressed under 300 and 600 MPa pressure. Composite materials produced at different pressures were subjected to sintering for 30, 60 and 90 min at temperatures of 300,400and 500oC and allowed to cool in the oven. The properties such as density, microstructure of Al-Mg/Al2O3 composites were investigated and characterized. Investigations of SEM, EDX, optic microscopy of specimens are made. Maximum porosity is measured as 0.93 at produced 300 MPa cold pressure, 500oC sintering temperature and 30 min. sintering temperature with % 15 Al2O3 composite.
