| Summary: | This study examined the previous research on the mechanical properties of
reinforced composites of aluminium-matrix, manufactured by stir casting.
Stir casting has been reported as the most economical fabrication method
currently in use for producing Aluminum Matrix Composites because of its
accessibility, portability, adaptability to be utilized for large-scale
manufacture, and easy operation of the application to conventional shape
casting foundry procedures. Apart from the minority report that recorded a
reduction in ductility, yield strength, ultimate tensile strength, and
modulus of elasticity but with an increase in hardness of the SiC
particulate reinforced aluminium matrix composites following the increase in
reinforcing material, the majority of work has shown that the mechanical
properties increase with the increase in the addition of the reinforcing
material. Reinforcing materials like silicon carbide, tungsten carbide,
alumina, boron carbide, and multi-walled carbon nanotubes have been used in
various compositions to manufacture aluminium-matrix composites. The
highest reported ultimate tensile strength of 489 MPa was obtained after
stir casting 10 vol% of SiC - aluminium matrix composite. The maximum
tensile strength of 401 MPa was attained with 20% B4C - Al-matrix composite.
Various uses of metal-matrix composites have been identified in the making
of hypersonic aircraft, sporting equipment, and automobile engine parts. |
