Abstract
<div class="section abstract"><div class="htmlview paragraph">In this research, the aim is to investigate the tensile properties and
microstructures of Aluminium 6061 hybrid composite before and after extrusion.
Aluminium 6061 Hybrid composite was fabricated using Stir casting technique with
6 Weight % silicon nitride (Si<sub>3</sub>N<sub>4</sub>) coated with nickel and
1Weight % carbon fiber (C<sub>f</sub>) coated with copper as reinforcements
followed by extrusion process. The tensile properties and microstructures of
extruded hybrid composite was investigated and compared with as-cast hybrid
composite. The microstructure of the hybrid composite showed excellent bonding
between matrix and reinforcements interface. The hot extruded hybrid composite
exhibited enhanced yield strength (44%), ultimate tensile strength (33%) and %
elongation (20%) when compared with as-cast hybrid composite. Scanning electron
microscopy (SEM) and Energy dispersive spectroscopy (EDS) techniques were used
to observe the fracture surfaces of tensile testing specimens.</div></div>
