Effect of SiC Amount on the Properties of Al6061 Matrix Produced by Powder Metallurgy

EasyChair Preprint 2610

Abstract

In the present study the effect of SiC amount on structural, physical and mechanical properties of Al matrix composite (AMCs) was investigated. Al6061 alloy and three composites were fabricated by powder metallurgy technique (0, 7.5, 10 and 13 wt.% of SiC). The prepared composites were characterized   by X-ray diffraction, optical microscopy and Vickers hardness. Physical properties (Density) of the prepared Al6061-SiC composites were measured. The microstructures show a homogeneous distribution of SiC nanoparticles into the aluminium matrix. We have found a significant increase of hardness and density of the composites with the increase of silicon carbide quantity. However, it is noticed that the porosity of Al-SiC composites decreases with the increase of SiC amount.
