Abstract

Aluminum and its alloys are widely used in automotive,
aviation, defense industries because of its low density, process ability, high
strength. Aluminum matrix composites are usually manufactured by powder
metallurgy or liquid methods. As a liquid processing method, stir casting
method is a cheaper and easier method than powder metallurgy. When waste
beverage cans are recycled and used as matrix material for manufacturing
composite material, cost of process is reduced and also environmental pollution
is reduced.  In this study, silicon carbide (SiC)
reinforced aluminum matrix composites have been manufactured. From the
manufactured composites specimens have been prepared and hardness, density,
compressive, tensile, tests; XRD and SEM analyses have been applied. From the
obtained results with the reinforcement of SiC, hardness value has been
increased from 70.1 HV to 89.90 HV. Also, from SEM analyses it is observed that
SiC particles have been dispersed homogeneously.

Keywords
