Aluminium Metal Matrix composites have replaced the major conventional materials because of its superior mechanical properties such as high strength, lesser weight and good wear resistance. Aluminumsilicon (LM series) metal matrix composite can fulfil the needs of emerging trends in engineering and industrial advancements. The present study attempted to review the researches undergone on the influence of various reinforcements such as ZrO2, TiB2, AlB2, SiC, MoS2, B4C, etc., on LM based aluminium alloys on their properties like tensile and compression strength, hardness, impact strength. The methodology of various papers has been studied and the corresponding conclusion was included in this study.

Aluminium metal matrix composite with higher tensile strength is made using a hybrid stir-squeeze casting technique. The hybrid technology combines the desirable features of uniform reinforcement particle distribution in the base matrix through stir casting and refined microstructure, minimizing porosity and enhanced mechanical properties via squeeze casting process. The composite was made from A356 aluminium alloy reinforced with Molybdenum disulfide (MoS2) and wheat husk ash (WHA). A356 alloy has a wide range of engineering applications, with MoS2 increasing wear resistance and WHA particles providing major technological and economic benefits. Taguchi L16 orthogonal array experiments are applied to optimize the stir-squeeze casting parameters (stirring speed, mould temperature, squeeze time squeeze pressure, pouring temperature) for achieving better tensile strength of the composites. The identified significant factors for the stir-squeeze casting process are stirring speed, squeeze pressure, and squeeze time. The optimum stir-squeeze casting condition increased the composite's tensile strength by 23.72%. The squeeze pressure of 125 MPa was noted that to eliminating these porosities and gives better grain refinement in the microstructure. The fractured tensile test specimen indicated the brittle and ductile mode of fracture.

Squeeze casting is one of the simplest processes of manufacturing of composite materials and it attains higher advantages of low material processing cost, easy handling of material, size, design and good stability of matrix structure. LM24 aluminium alloy reinforced with silicon carbide (SiC) and coconut shell ash (CSA) were used to prepare the composite. LM24 alloy had wide engineering applications, wherein the addition of SiC enhances the wear resistance and CSA particles offer significant technical and economic benefits. In the present study, the composite samples were prepared based on Taguchi experimental conditions L16 (4-levels and 5- parameters) through squeeze casting method. From the experimental results, percentage of reinforcement and squeeze pressure were most influential parameters on impact strength. The optimum casting condition was obtained by using Taguchi optimization. From microstructural study, applying high level of squeeze pressure improved the uniform dispersion, good bonding between the matrix and reinforcement. Also, 25% of impact strength was improved the composite using Taguchi optimum conditions compared than conventional alloys. Higher squeeze pressure seen to have refined dendritic structure with uniform distribution of reinforcement materials in the aluminium matrix.
