“…Al 8011-6wt.%SiC showed higher hardness and tensile strength, but Al8011-2wt.%SiC showed better elongation and toughness. Particle size was identified as the primary element impacting mechanical characteristics, with reinforcing quantity being the next most significant component [9]. The review article examines the wide range of uses of Aluminium (Al) or Aluminium alloy Metal Matrix Composites (MMCs) in sectors such as aerospace and automotive because of its lightweight nature, high tensile strength, and resistance to wear.…”

The growth of the industrial sector has resulted in a higher use of Aluminium Metal Matrix Composites (AMMCs). These composites are well-known for their exceptional mechanical and tribological qualities, attracting worldwide attention, especially in the automotive, architectural, and aerospace industries. Advanced Metal Matrix Composites (AMMCs) exhibit increased specific strength, improved strength-to-weight ratio at increasing temperatures, and better wear resistance when compared to the basic matrix without any additional components. SiC and B4C particle reinforcements are used to enhance the metallurgical and mechanical characteristics of the base matrix. Authors have used several production methods such as Powder Metallurgy for solid-state procedures and Stir Casting, Compo-casting, Squeeze Casting, and in-situ casting for liquid-state processes to create AMMCs. Stir casting is the most cost-effective and easy process for producing AMMC. This article provides an in-depth explanation of the procedure for producing Aluminium Matrix Metal Composites (AMMCs) utilising AL-7175 as the matrix material, together with B4C and SiC as reinforcements, with the stir casting technique.

In order to increase system efficiency, lightweight materials are crucial in the automotive and aerospace sectors. In this work, iron oxide (Fe2O3) and cobalt (Co) were used as reinforcements, with aluminium alloy AA2014 serving as the matrix material. The metal matrix composites were made using the stir casting technique. The proportions of iron oxide and cobalt utilised as reinforcement in the composites were 2.5 wt % and 5 wt %, respectively. On the composite specimen created in accordance with ASTM E8, E9, and E23 standards, the mechanical properties of tensile, flexural, and impact strength were investigated. Investigations were also done on the hardness of the composites. The morphology of the composites was examined using an optical microscope.

“…Al-20 wt.% B 4 C has a maximum Vickers hardness at 850 C. 9 Pradhan et al has studied that the hardness and tensile strength of Al-Al 13 Fe composite is improved without affecting the ductility of metallic matrix. 10 Dinaharan et al examined the various properties of Cu-(SiC, Al 2 O 3 , TiC and B 4 C) metal matrix composite developed by friction stir process. Copper-B 4 C has higher hardness and wear resistance as compared to other copper matrix composite.…”

The aim of the present paper is to examine the outcome of Al2O3-SiC reinforcements on structural and mechanical behavior of Al matrix based hybrid composites. Al-Al2O3-SiC hybrid composite has been developed through stir casting with addition of ceramics i.e. Al2O3-SiC (2.5 wt.%, 5.0 wt.%, 7.5 wt.% and 10.0 wt.%) in relative and symmetrical proportion. The structural characteristics, i.e. phase, microstructure, EDS; physical property i.e. density and the mechanical properties, i.e. hardness, impact strength and tensile strength of fabricated specimens have been investigated. XRD represents the transitional phase formation among Al base material and Al2O3-SiC ceramic phases with inter-atomic bonding between them. SEM reveals that the Al2O3-SiC fragments has distributed symmetrically in Al matrix. EDS spectrum of various samples are in confirmation with the XRD results. Density of hybrid composite reduces with increase in weight percentage of ceramic reinforcements i.e. Al2O3-SiC because ceramic particle gains low density after preheating. Hardness of hybrid composites increases upto 5 wt.% variation of ceramic reinforcements i.e. Al2O3-SiC after that it decreases. Impact strength of hybrid composite has been increased with an increase in weight percentage of ceramic. Al-2.5 wt.% Al2O3-2.5 wt.% SiC shows maximum ultimate tensile strength. It is expected that the prepared hybrid composites will be useful for fastener studs.
