Study on mechanical properties of Metal Matrix Composites (MMCs) Al-Cu-Mg/SiCp with Powder Metallurgy

Abstract

The synthesis of aluminum (Al) alloys, Al-Cu-Mg from mixture powder 88.4 wt% Al; 3.8 wt% Cu and 1.8 wt% Mg the adding 6.0 wt% up to 7.0 wt% of SiCp on Al-Cu-Mg. After mixing the sample has been prepared by hot pressing process at a temperature of 350oC. After pressing sample has prepared by sintering one hour at a temperature 500oC and aging 16 hours. Al-Cu-Mg/SiCp alloys samples has been investigated. The structure analysis were examined by X-Ray Diffractometer (XRD) and scanning electron microscope (SEM-EDX). The hardness was measured by hardness Vickers method. According to the results, it can be assumed that the 7 wt% of SiCp content is prefer content to get better quality of hardness Vickers of Al-Cu-Mg alloys.
