“…Furthermore, the investigators observed that the hardness of the hybrid composite is higher than that of the mono composite due to the presence of SiC particles. Pugazhenthi et al [44] studied the influence of solidification on the hardness of the Al/TiC/Gr hybrid composites. The hardness increased with an increase in the cooling rate, attributed to the TiC particles impeding the dislocation in the Al-matrix.…”

This review briefs the vortex casting and hardness of mono aluminium matrix composites (AMCs) and hybrid AMCs (HAMCs) containing lamellar solids (Gr (graphite) or MoS2 particles). The vortex addition process and the associated process parameters to fabricate the mono and hybrid AMCs are discussed. The Gr particles are coated with Ni or Cu where they alloyed with the melt to enhance the wettability. Furthermore, the addition of alloying elements and the particle preheating improve the wetting of the uncoated lamellar solids with the melt. The Gr-reinforced or MoS2 reinforced mono AMCs exhibited a decrease in hardness with the addition of lamellar solids. In HAMCs, the ceramic particles resist the indentation, leading to their better hardness than the lamellar solid reinforced mono AMCs.

In the current research, titanium carbide (TiC) is used to reinforce the aluminium alloy (AA 6063) in stir-cast hybrid composites at concentrations of 5, 10, and 15 weight percent together with 3 weight percent of graphite. The application of this developed composite is mainly used for automobile suspension parts. The portrayal of characters was performed, and the mechanical properties of the fabricated samples were investigated. Composites with different TiC weight percentages have their mechanical properties, including hardness, tensile strength, compressive strength, and flexural strength, measured and assessed. The results are shows that AA 6063 alloy with 3 wt. percentage of graphite with an increasing weight percentage of TiC composites are better in the mechanical property. The hardness of the AA 6063 alloy composites is greater than that of the base matrix alloy. The tensile strength of Al 6063 alloy composites has been reported to grow with increasing TiC particle content and to be significantly higher than the strength of the matrix alloy. Also, the SEM microstructure images clearly shows that 15 weight percentage of TiC with 3 weight percentage of Graphite shows the maximum distribution in the matrix.
