Abstract: Aluminium alloys are widely utilised in the aerospace and automobile industries due to their low density and strong mechanical qualities, as well as their superior corrosion and wear resistance and low thermal coefficient of expansion as compared to traditional metals and alloys. These material’s superior mechanical qualities and inexpensive production costs make them an appealing alternative for a wide range of scientific and technical applications. In this study, we strive to present a literature review on the overall performance of reinforced composites created by the stir casting method, as well as the effect of process factors on the properties of Aluminium-based MMC. The literature review framework in this paper provides a clear overview that the process parameters play important role for optimum properties of Aluminium based Metal Matrix Composites. As reinforcing elements in Metal Matrix Composites, Boron Carbide and Silicon Carbide play an important role. The MMCs were successfully produced using the liquid metallurgy process. Scanning electron microscopy was used to examine the morphology and microstructure of Al-B4C and Al-SiC composites. The addition of 2, 4 and 6 wt% B4C and SiC particles increased several mechanical parameters such as ultimate tensile strength and hardness. It was also discovered that the mechanical behaviour of B4C particulates AMC is superior to that of SiC particulates AMC. Keywords: Aluminum, Metal matrix composite, SiC, B4C, Tensile test, Hardness test and SEM Analysis.

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.

Aluminum Metal Matrix Composites

Abstract An increased interest is observed in recent years in the processing of aluminum metal matrix composites (AMMCs) due to their remarkable properties such as light in weight, very high strength, environmental resistance, corrosion resistance, and low thermal coefficient of expansion compared to conventional metal and alloys. This leads to superior compressive strength, for fuel cell applications, low density and low cost for automotive and small engine applications. Homogeneous distribution of the reinforcement phase in turns improves hardness and ultimate tensile strength for lightweight applications, especially aeronautical and high-speed train industries. Uniform distribution of reinforcement directly influences properties and quality of the composite material. And develop a conventional low-cost method of producing metal matrix composites to obtain a homogenous dispersion of reinforcing materials. In this review article, processing and characterization of aluminum metal matrix composites have been reviewed. The Point of convergence is given to the new fabrication techniques, their physical and mechanical characterization. Substantially this review article censoriously reviews the present and past state of understanding of the processing of aluminum metal matrix composites with different reinforcement. The resulting failure mechanisms are discussed. Instructions are given to clarify open questions related to the fabrications of aluminum metal matrix composites.

Network Simulation Method

A simple model based on the network simulation method is proposed to estimate numerically the thermal conductivity of particulate reinforced metal-matrix composites. The estimation is carried out running the model in the standard Pspice code, the computing time being negligible. The 3-D solid is discretized in 1000 cubic volume elements which represent an acceptable approximation of the shape of the particles. For each reinforcement percentage and each combination of matrix and reinforcement more than 200 tests were carried out, so that the results may be considered close to the exact values. The limit values are scarcely influenced by the effect of the 3-D geometry and basically depend on the amount of the reinforcement. Applications to aluminum and titanium matrix composites reinforced with different types of particles are presented covering a wide range of reinforcement percentages.
