AbstractMetal is the one of the important material in engineering materials because of their high strength to weight ratio. However the pure metals cannot be used as engineering materials due to their ductile property. So, to improve their mechanical properties, some of the high strength materials (not metals) were added as reinforcement to improve the mechanical properties of pure metals and the newly developed material is called as metal matrix composites. At present, Aluminium, Copper, Magnesium, Titanium and Iron have been used as matrix materials and materials like TiC, SiC, B4C, WC, Cr3 C, TiO2, ZrO2, Gr, MoS2 and Si3N4 have been used as reinforcements. There are many processing techniques to fabricate metal matrix composites namely stir casting, ultra-sonic assisted casting, compo-casting, rheo casting, powder metallurgy technique, etc,. Among these, stir casting process is the most suitable and economical method to fabricate the metal matrix composites. In this article, an effort has been made to review the work of various researchers to fabricate metal matrix composites through stir casting process.

This paper deals about the importance of composites as engineering materials which is reflected by the fact that most of the materials which are available in the market are composites. These composites replaced cast iron and bronze alloys due to their poor wear and seizure resistance. Due to the wide choice of materials, today's engineers are posed with a big challenge for the right selection of a material and the right selection of a manufacturing process for an application. There are more than 50,000 materials available to engineers for the design and manufacturing of products for various applications. In the present study, based on literature review, the effect of Boron Carbide particle reinforcements are finding increased applications in aerospace, automobile, space, underwater and transportation applications. This is mainly due to improved mechanical and tribological properties like strong, stiff abrasion and impact resistant and it is not easily corroded. In a review of different researchers have been made to consolidate some of the aspects of mechanical and wear behaviour of Aluminium Metal Matrix Composites reinforced with Boron Carbide particles.

Aluminium Matrix Composites (AMCs) are known as lightweight and high-strength materials with potential applications in areas such as aerospace, automobile, defence, engineering, and other industries. AMCs have the advantage of significantly reduce the overall weight of the vehicles and aircraft while maintaining their structural strength. The scope of this work is to fabricate Silicon Carbide (SiC) particle Metal Matrix Composites (MMC) by stir casting combined with mechanical stirring and to investigate the effect of SiC particles on the hardness, tensile and impact the behaviour of SiC particle reinforced 7075 aluminium alloy composites. The reinforcement of micron-sized range particles with an aluminium matrix is expected to improve the mechanical properties in composite materials. Different weight % of SiC particles are used (0, 5, 10, and 15 wt. %) for the synthesis of composites. The manufactured composites were tested to determine their mechanical properties and the results prove that the sample with 10 percentage of silicon carbide has better mechanical properties, comparably.

Aa 7075

Aluminium alloy (AA7075) is largely used in various fields of transport applications, including marine, automotive and aviation and aerospace due to their high strength-to-density ratio. The present work deals with the influence of TiC on the mechanical behavior of AA 7075 composites. TiC is particularly attractive as it offers high hardness and elastic modulus, low density, good wettability yet low chemical reactivity with aluminium melts. The aluminium metal matrix composites (AMMCs) are produced as AA 7075 matrix metal and TiC particulates of an average size of 2µm as reinforced particles through stir casting, Magnesium added to the melt to overcome the wetting problem between TiC and liquid AA7075 metal. AMMCs are produced in different %weight of TiC ranging between 2 to 10%.These composites are characterized with optical, SEM and EDS analysis in as-cast condition and T6condition and hardness are predicted using macro vickers hardness tester. The test results showed increasing hardness of composites compared with matrix (AA7075) because of the presence of the increased reinforced material (TiC)

AbstractThe effects of micro and nano sized reinforcement particles on microstructure and mechanical properties of aluminium alloy-based metal matrix composites were investigated in this study. AlSi9Cu3 alloy was reinforced with micro and nano sized ceramic reinforcement particles at different weight fractions by using a stir casting method. The mechanical tests (hardness, three point bending) were performed to determine the mechanical properties of AlSi9Cu3 alloy-based microcomposites (AMMCs) and nanocomposites (AMMNCs). The experimental results have shown that the size and weight fraction of reinforcement particles have a strong influence on the microstructure and the mechanical properties of AlSi9Cu3 alloy-based microcomposites and nanocomposites. The relative densities of all AMMC and AMMNC samples are lower than unreinforced AlSi9Cu3 alloy due to porosity formation with the increase of weight fraction of reinforcement particles. As weight fraction increases, hardness values of AMMCs and AMMNCs increase. Maximum flexural strength can be obtained at 3.5wt.% for the AMMC sample with microsized Al2O3 particles and at 2wt.% for the AMMNC sample with nano-sized Al2O3 particles. After the weight fractions exceed these values, flexural strengths of both AMMCs and AMMNCs decrease due to clustering of Al2O3 particles.

It is well known that the addition of ceramic phases in an alloy e.g. aluminum, in form of fibers or particles influences its mechanical properties. This leads to a new generation of materials, which are called metal matrix composites (MMCs). They have found a lot of application during the last twenty-five years due to their low density, high strength and toughness, good fatigue and wear resistance. Aluminum matrix composites reinforced by ceramic particles are well known for their good thermophysical and mechanical properties. As a result, during the last years, there has been a considerable interest in using aluminum metal matrix composites in the automobile industry. Automobile industry use aluminum alloy matrix composites reinforced with SiC or Al2O3 particles for the production of pistons, brake rotors, calipers and liners. However, no reference could be cited in the international literature concerning aluminum reinforced with TiB particles and Fe and Cr, although these composites are very promising for improving the mechanical properties of this metal without significantly alter its corrosion behavior. Several processing techniques have been developed for the production of reinforced aluminum alloys. This paper is concerned with the study of TiB, Fe and Cr reinforced aluminum produced by the stir-casting method.
