Now a day’s Hybrid Metal Matrix composites has a large number of applications in automobiles, aircrafts and structural applications like brake rotors, engine parts and cylinder liners. The aim of this study is to determine the mechanical properties of boron carbide (B4C) and zirconium silicate (ZrSiO4) particulate reinforced with AA6063 alloy composites. In this experimental study, B4C and ZrSiO4 particulates reinforced with AA6063 composites were manufactured by stir casting technique. Mechanical properties of these composite materials were investigated by different weight percentages, 3%, 6%, 9% of boron carbide (B4C) and 9%, 6%, 3% of zirconium silicate (ZrSiO4) respectively. The mechanical properties evaluation reveals variations in hardness and the tensile strength values with the composite combinations investigated in this work. From the experimental studies, the optimum volume fraction of hybrid reinforcement in AA6063 alloy on the basis of mechanical properties and SEM analysis is also determined.

AbstractA significant materials-based activity to develop Ti-aluminide metal matrix composites for high temperature aerospace structural applications is now underway. A review of the approaches, progress, and status of the development of continuously-reinforced Ti-aluminide metal matrix composites with matrices which contain a significant volume fraction of the ordered orthorhombic Ti2AlNb phase will be presented. The principal application considered is a gas turbine compressor rotor ring, and this influences the development approaches and properties goals. Specific development activity that will be presented includes modification and control of the matrix composition and microstructure, fiber coating treatments to control interdiffusion between the fiber and the matrix, and to improve the ability of the interface to support a mechanical load, and efforts to improve the properties of SiC monofilaments used as reinforcements. Critical issues that define the requirements for additional studies will be presented.

Structural Applications

Aluminium based Metal Matrix Composites (MMCs) with Aluminium matrix and non-metallic reinforcements are finding extensive applications in automotive, aerospace and defence fields because of their high strength-to-weight ratio, high stiffness, hardness, wear-resistance, high-temperature resistance, etc. Composite materials are frequently chosen for structural applications because they have desirable combinations of mechanical characteristics. Development of hybrid metal matrix composites has become an important area of research interest in Material Science. In this work, the Aluminium alloy is reinforced with 3,5,7,9 wt. % of Al2O3 and 2 wt. % of SiC to prepare the hybrid composite. The present study is aimed at evaluating the physical properties of aluminium 7075 in the presence of silicon carbide, aluminium oxide and its combinations. The compositions are added up to the ultimate level and stir casting method is used for the fabrication of aluminium metal matrix composites. The mechanical behaviours of metal matrix composites like tensile strength, and hardness test are investigated by conducting laboratory experiments. Mechanical properties like micro hardness and tensile strength of Al7075 alloy increase with the addition of SiC and Al2O3 reinforcements.

Metal Matrix Composites possesses high mechanical properties compared to unreinforced materials. Aluminium Matrix Composites (AMC) is attracted in the emerging world because of its low cost, less weight and enhanced mechanical properties. In the present study the enhancement in mechanical properties like hardness and tensile strength of AMCs by reinforcing AA 6061 matrix with silicon carbide (SiC) and boron carbide (B4C) particles are analyzed. By enhanced stir casting method aluminium matrix was reinforced with boron carbide particulates and silicon carbide particulates with the various weight percentage of 2.5 %,5% and 7.5%.The tensile strength and hardness was found to increase with the increase in wt% of the reinforcement. From the analysis it is observed that the mechanical property of B4C reinforced AMC is significantly good compared to SiC reinforced AMC.

By using the advantages of carbon nanotubes (CNTs), such as their excellent mechanical properties and low density, CNT-reinforced metal matrix composites (MMCs) are expected to overcome the limitations of conventional metal materials, i.e., their high density and low ductility. To understand the behavior of composite materials, it is necessary to observe the behavior at the molecular level and to understand the effect of various factors, such as the radius and content of CNTs. Therefore, in this study, the effect of the CNT radius and content on the mechanical properties of CNT-Al composites was observed using a series of molecular dynamics simulations, particularly focusing on MMCs with a high CNT content and large CNT diameter. The mechanical properties, such as the strength and stiffness, were increased with an increasing CNT radius. As the CNT content increased, the strength and stiffness increased; however, the fracture strain was not affected. The behavior of double-walled carbon nanotubes (DWNTs) and single-walled carbon nanotubes (SWNTs) was compared through the decomposition of the stress–strain curve and observations of the atomic stress field. The fracture strain increased significantly for SWNT-Al as the tensile force was applied in the axial direction of the armchair CNTs. In the case of DWNTs, an early failure was initiated at the inner CNTs. In addition, the change in the elastic modulus according to the CNT content was predicted using the modified rule of mixture. This study is expected to be useful for the design and development of high-performance MMCs reinforced by CNTs.
