Notched behaviour of a silicon carbide particulate reinforced aluminium alloy matrix composite

The modern vehicles demand more thermal and mechanical properties as the speed of the vehicles is increasing. The materials used should be able to not only withstand the high temperatures but to dissipate it at a faster rate without deformation. This paper investigates the characteristics of silicon carbide (SiC) and fly ash in LM13 aluminium alloy matrix composite prepared by stir casting. The LM13 alloy has high thermal property which makes it ideal for making engines and gears. The effect of fly ash and SiC on LM13 and its influence on increasing the surface roughness was analyzed by varying their proportion. The addition of SiC and fly ash to the matrix composite increases the hardness and tensile strength of the composite which is validated by experimental results.

The effects of subjecting solidifying particulate reinforced aluminium alloy matrix composite to various sources of vibration on the resulting casting quality, a mechanical vibration technique for inducing vibration resulting in enhanced mechanical properties, such as impact properties is devised. TiC particulate reinforced LM6 alloy matrix composites are fabricated by different particulate weight fraction of titanium dioxide and microstructure studies were conducted to determine the impact strength and density, respectively. Preliminary works show that the mechanical properties have been improved by using vibration mold during solidification compared to gravity castings without vibration.
