Abstract:
Aluminium metal matrix composites have been shown to make significant contributions to the area of new materials and have become widely accepted in high-tech structural and functional applications such as those in the aircraft, automobile, marine, mineral, defence, transportation, thermal management, automotive, and sports and recreation fields. Metal matrix composites are manufactured using a variety of manufacturing processes. Stirring casting, powder metallurgy, squeezing casting, in situ processes, deposition techniques, and electroplating are part of the manufacturing process used in the manufacture of aluminium-metal matrix composites. Metal matrix composites that use friction stir processing have a distinct advantage over metal matrix composites that use other manufacturing techniques. FSP’s benefits include a finer grain, processing zone homogeneity, densification, and the homogenization of aluminium alloy and composite precipitates. Most metal matrix composite investigations achieve aluminium-metal matrix composite precipitate grain refinement, treated zone homogeneity, densification, and homogenization. This part of the work examines the impact of reinforcing particles, process parameters, multiple passes, and active cooling on mechanical properties during the fabrication of 5000-series aluminium-metal matrix composites using friction stir processing. This paper reports on the available literature on aluminium metal matrix composites fabricated with 5xxx series marine grade aluminium alloy using FSP.

Abstract:
Aluminium-matrix composite is one of the most preferred engineering materials and is known for its potential benefits, such as lightweight nature, high specific stiffness, superior strength, machinability, etc. The metal–matrix composites are very attractive for critical applications: Aerospace field, defense deployments, automotive sector, marine industry. In the present work, novel Physella Acuta Snail Shell particle reinforced aluminium metal–matrix composites are developed to facilitate cost-effective and sustainable manufacturing. These green composites are developed by stir-casting with LM0 as matrix material and snail shell as reinforcement with a distinct percentage (by weight) of inclusion. The influence of snail shells is analyzed through tribological, morphological, and corrosion studies. Aluminium–matrix composite Al98SNS2 with 98% (by weight) aluminium matrix and 2% (by weight) snail shell reinforcement exhibits superior performance in all investigations. Al98SNS2 composite exhibits the least wear rate in the atmosphere of deionized water and 3.5% NaCl. Corrosion deteriorates the surface roughness irrespective of the percentage of incorporation of snail shell reinforcement. However, the deterioration is minimal in Al98SNS2. The current research findings indicate that the incorporation of snail shell in aluminum metal–matrix composites promotes cost-effective, sustainable, and eco-friendly manufacturing.

Abstract:
In the present study aluminium silicon carbide (Al/SiC) composites were prepared by powder metallurgical method. The mechanical and morphological evaluation were studied upon the variation of reinforcements percentages i.e.10, 15 and 20 wt.% of SiC powder were used as the reinforcements in aluminium matrix. The comparison of powder metallurgy method with stir casting method of Al/ (SiC) composites preparation was performed and the particle reinforcements were visualized through Scanning Electron Microscopy (SEM). The results demonstrated increased hardness with increasing wt. % of SiC particles. This was attributed to efficient stress transfer and dislocation strengthening. In addition, the densification behaviour of the composites was also studied and SiC particulates were found to exhibit profound effect on composites density.

Abstract:
Metal matrix composite materials are a novel material generation capable of handling the implementation of advanced technology's growing needs. Aluminium-based metal matrix composites are widely used in automobiles and aerospace, as well as other industries, including defence and marine systems, due to their relatively low processing costs as compared to other matrices such as magnesium, copper, titanium, and zinc. Ceramic particles were shown to improve mechanical properties like hardness and tensile strength. The product's compactness and price, however, were both boosted. Agricultural waste materials are widely available today in significant amounts, and researchers have focused on using wastes as reinforcing fillers in composites to counteract pollution. Rice husk ash added to an aluminium alloy matrix increases the composite's mechanical properties while also increasing its wear resistance. According to scanning electron micrographs of the composite, the ash from rice husks is evenly distributed all over the aluminium matrix. Wear can vary from micro-cutting to oxidation at high temperatures in an aluminium alloy. Strain fields are produced and composite material wear resistance is improved due to the difference in coefficients of thermal expansion between the matrix and reinforcing materials. This study focuses on the production process, properties, and performance of an aluminium alloy composite incorporating rice husk ash, which has high hardness as well as wear resistance.

Abstract:
Due to their superior capabilities for manufacturing lightweight automotive components, aluminium metal matrix composites have gained a lot of attention in the last few years. Aluminium metal matrix composites are an exceptional class of metal matrix composites that can solve all the major problems related to the automobile industry. Aluminium matrix composites in the disc braking system have already been employed and studied by many scientists. However, the developed materials are not yet always sufficiently accurate and reliable. In this article, a new enhanced metal matrix composite material is used and studied to improve the efficiency of an ordinary car’s braking system. To improve the accuracy of the designated braking system, an innovative hybrid aluminium matrix composite (Al6061/SiC/Gr)-based brake rotor has been developed, and its effectiveness has been determined by finite element analysis. From the simulation, the product performance confirmed that the hybrid aluminium matrix composite (Al6061/SiC/Gr)-based brake rotor has the potential to replace the standard cast iron brake disc. The new enhanced hybrid composite material used in this study can be used for the efficient design of various braking parts.

Abstract:
Aluminium matrix composite is a type of innovative technical material that have applications in aerospace, automotive, biotechnology, electronics, and a lot more. Non-metallic reinforcements can be injected into an aluminium alloy to provide advantages over base metal (Al) alloys. Better mechanical properties, improved microstructure, and corrosion resistance are the benefits that have been noticed upon reinforcements. The proportion of reinforcement, kind, size, and forms of aluminium matrix are all important factors in improving mechanical and tribological properties. Investigation in the creation of highly advanced tailored materials using liquid and solid-state processes and the impact it has on the properties and application are the subject of this work. The current research summarizes recent breakthroughs in aluminium-based composites and other particle reinforcement effects. The experiment findings revealed that strengthening the aluminum matrix with reinforcements increased mechanical properties and improves the microstructure. Also, stir casting was seen to be the most popular liquid metal approach because of its cost effectiveness and processing parameters which could easily be adjusted and monitored. It is concluded that aluminum matrix composites have greater mechanical characteristics, microstructure, and corrosion resistance than unreinforced aluminum alloys.

Abstract:
Abstract Metal matrix composites become interesting for use as constructional and functional materials. The development of metal matrix composites was primarily directed to the continuous-fibre reinforced metal matrix composites - such as boron fibre/aluminium-based matrix, continuous alumina fibres /aluminium-based matrix, graphite fibre/aluminium-based matrix or graphite fibre/magnesium-based matrix composites. Despite the successful production of these metal matrix composites, they manufacturing was limited by the concerns related to the technological processes and cost, their availability remaining a significant barrier to their manufacturing. The benefits of metal matrix composites as compared to the unreinforced (monolithic) metals or alloys include superior mechanical and physical properties that deliver improved structural performance. This concept also further implies re-using materials or using recycled materials. Therefore, discontinuously reinforced metal matrix composites are suitable for a wide range of industrial applications. This study aims to investigate the developments in area of solving the needs for the matrix material necessary for the discontinuously reinforced aluminium matrix composites. Aluminium can be recycled directly back into itself over and over again in a true closed loop.

Abstract:
The trend towards the use of composites is increasing rapidly in the ongoing scenario and is likely to increase more rapidly in the future. Nowadays aluminium and its alloy based composites are gaining importance in the upcoming fields of engineering. Aluminium metal matrix composite (AMMC) possess superior strength, hardness, corrosion resistance, fatigue and creep resistance in addition to low weight advantage of aluminium. Aluminium based composites (AMMC) are widely used in aerospace and automotive industries due to high strength to wear ratio. Mechanical Components due to insufficient strength fails under various types of loading. Modern mechanical components require advance properties, the material available in pure form do not possess the required strength, hardness, corrosion resistance etc. A Composite is formed by combination of two or more physically and chemically distinct substances and is fabricated to enhance the characteristics of base metal. The material is then characterized by the different types of analysis like tensile, impact, hardness, along with thermal analysis such as XRD and DTA. Metal matrix composite (MMC) are formed when the base metal is metal and reinforcement takes place in the form of powder, particles, fibers and whiskers. Reinforcements in the metal matrix composite may be a metal or other material which may be ceramic or any other organic compound. Metal matrix composites (MMC) possess significantly enhanced properties which improve the functioning as well as service life of the various mechanical components. This paper is aimed to review the theory, experiments and methodology to fabricate aluminium metal matrix composites (AMMC) and also the characterization of fabricated material.

Abstract:
The design of aluminium–graphite metal matrix composites (MMCs) with advanced mechanical properties and high corrosion resistance is in demand for aerospace, transportation, and industrial applications. Breakthroughs in this field are limited due to the tendency of aluminium–graphite MMCs to corrode. In the present research, aluminium-based MMCs were produced by a relatively novel combined two-staged method. Multiwall carbon nanotubes (MWCNTs) were added into molten Al1070 and processed by high-pressure die casting followed by cyclic extrusion. For the composites produced by this method, it was previously demonstrated that mechanical properties are improved in comparison with pure aluminium alloys. In the current study, the manufactured Al–MWCNT composites were investigated by electrochemical tests (such as open circuit potential), potentiodynamic tests, linear polarization tests, and electrochemical impedance spectra to understand the corrosion resistance of the obtained composite material. The experimental testing of the corrosion resistance of Al–MWCNT MMCs showed that due to the advantages of the fabrication method, the addition of CNTs to aluminium does not cause a radical decrease of corrosion resistance.

Aluminium, being the second most abundant metal in earth’s crust, has emerged as an important metal in human civilization’s development. It has served as an excellent substitute for many conventional materials like wood, copper, iron and steel. Now a days, more Aluminium is consumed (on a volumetric basis) than all other non-ferrous metals/alloys including copper.Aluminium and aluminium alloy are gaining huge industrial significance because of their good combination of mechanical, physical properties over the base alloy. In some few recent years the use of metal matrix composite material increases very rapidly due to their high weight to strength ratio, low density, low thermal expansion coefficient, low maintenance and high temperature resistance. Metal matrix composites are widely used in aerospace and automotive engine components. The aluminum alloys are reinforced with Al2O3, B4C and TiC and fabricated by stir casting, centrifugal casting, and powder metallurgy process. In the fabricated metal matrix composites some different tests were conducted to show mechanical properties, micro-structural characterizations of materials were also done.

The microstructure studies carried using optical microscope revealed the presence of Zirconium dioxide particulates in the Aluminium matrix. Also it revealed the uniform distribution of Zirconium dioxide in the Aluminium matrix and no voids and porosity were present in the matrix. The tensile strength and hardness properties were more than the base metal aluminium alloy. The tensile strength and hardness properties were increased with the increase in percentage of Zirconium dioxide up to 9% and decreased there afterwards. The optimum value for hardness and tensile strength of the composite was obtained at 9% of Zirconium dioxide.

Abstract:
In recent times, it could be observed that metal matrix composites receive considerable importance on account of improved properties compared to unreinforced alloys which includes high specific strength, specific modulus, damping capacity and good wear resistance. Interest in composites containing low density and low cost reinforcements has been since growing. Among various discontinuous particulate, silica is one of the most inexpensive and low density reinforcement available in large quantities. Hence, composites with aluminium oxide as reinforcement after the in-situ reaction of aluminium and silica are likely to overcome the cost barrier for wide spread applications in automotive and small engine applications. It is therefore expected that the incorporation of aluminium oxide particles in aluminium alloy will improve the mechanical properties of base material that will see increased usage in aircraft application due to reduced weight. In this research an effect on aluminum matrix composite reinforced with nano sized silica particles with different weight percentage was carried out. From the results it was found that the composites with 4 to 6wt% particle volume fraction to be the best with good tensile strength, yield stress and percentage elongation.

Its benefit is its simplicity, durability, and adaptability. The main issue in this process is proper wetting of reinforcement in aluminium matrix material. Only proper wetting results in a homogeneous dispersion of reinforcement material, and these homogeneous dispersions help to improve the properties of metal matrix composite material.

Abstract:
Composite materials are important engineering materials due to their outstanding mechanical properties. Composites are materials in which the desirable properties of separate materials are combined by mechanically binding them together. Each of the components retains its structure and characteristic, but the composite generally possesses better properties. Composite materials offer superior properties to conventional alloys for various applications as they have high stiffness, strength and wear resistance. The development of these materials started with the production of continuous-fiber-reinforced composites. The high cost and difficulty of processing these composites restricted their application and led to the development of discontinuously reinforced composites. The aim involved in designing metal matrix composite materials is to combine the desirable attributes of metals and ceramics. The addition of high strength, high modulus refractory particles to a ductile metal matrix produce a material whose mechanical properties are intermediate between the matrix alloy and the ceramic reinforcement. Metal Matrix Composites with Aluminum as metal matrix is the burning area for research now a days.

The paper presents the results of experimental investigation on the characterization and analysis of mechanical properties of composites formed. Three aluminum metal matrix composites reinforced with 10 wt% of B4C, SiC and Al2O3 particles were processed. The stir casting method followed by hot rolling was used for fabrications of aluminium 7075 metal matrix composites, being one of the cost effective industrial methods. Experimental results show nearly a uniform distribution and good dispersion of reinforced particles within aluminium matrix. Both tensile strength and hardness are enhanced by incorporation of reinforcement particles into the matrix. Scanning electron microscope (SEM) analysis was done to study the good dispersion of particles and surface characteristics.

Abstract:
This research paper deals with the preparation process and testing of metal matrix composites comprising Aluminium alloy (Al 6061) as the base metal and Titanium oxide (TiO2) and Graphite (Gr) as reinforcements. Due to their high specific strength, superior malleability, lightweight, stiffness and excellent resistance to corrosion, oxidation and wear, the aluminium metal matrix composites are preferred in the automobile and industrial sectors for component manufacturing. No work reported on machinability properties of Titanium oxide (TiO2) and Graphite (Gr) reinforced aluminium composites so far. This study prepared and studied samples composed of variable proportions of titanium oxide and graphite. The samples were prepared using the stir casting method. While stirring, the required additives were added to the molten aluminium mixture. To perform the tests, the samples were prepared according to standard dimensions after solidification. The mechanical properties of the prepared composite were examined using various test procedures, such as strength and hardness. Scanning electron microscopy was used to examine the microstructure of the test composite samples. The EDAX test confirmed the presence of graphite and Titanium oxide in the aluminium based composite specimens. Furthermore, machining was done to study the cutting forces on the tool. The test results showed a significant impact of the reinforced materials on the mechanical and machinability properties of aluminium metal matrix composites. Gr decreases hardness, while TiO2 increases it. TiO2 and Gr reinforcements increase the tensile strength of Al 6061 composites. The addition of TiO2 decreased the composite's elongation. The proof strength of 2 % Al6061 was high, however it decreased with 3 % Gr and increased with TiO2 reinforcement. Reinforcements increase cutting forces during machining; when comparing the machining of Al 6061 to that of 3 % Gr and 5 % TiO2, a 50 % increase in cutting forces is noticed. However, excessive reinforcements may reduce cutting forces due to poor matrix-reinforcement adhesion. HIGHLIGHTS The mechanical and machinability properties of aluminium metal metrics reinforced with Titanium oxide (TiO2) and graphite (Gr) have not been reported so far in the literature. In this study, aluminium based composites reinforced with variable proportions of titanium oxide and graphite were prepared and studied. The fabrication process was done by stir casting by adding the required additives into the molten mixture of aluminium, followed by continuous stirring. The solidified samples were cut according to the standard dimensions and various test procedures were conducted to examine the mechanical and machinability properties of the prepared composites. Gr reduces hardness, whereas TiO2 enhances it. TiO2 and Gr reinforcements boost Al 6061 composite tensile strength. TiO2 addition reduced elongation of the composite. 2 % proof strength of Al 6061 was strong, however it dropped with 3 % Gr and rose with TiO2 reinforcement. Reinforcements results higher cutting forces while machining, however excessive supplements lower cutting forces may be due to poor matrix-reinforcement bonding. GRAPHICAL ABSTRACT

Abstract:
Aluminium matrix composites are one of the most important classes of materials and have become a major focus of attention in aerospace, aeronautical, defense, and automotive industries. Aluminium matrix composites when compared to conventional alloys offer various promising properties like excellent strength-to-weight ratio, higher stiffness, lower coefficient of thermal expansion, better dimensional stability, and tribological behavior. The properties of aluminium matrix composites are highly influenced by the appropriate selection of metal matrix, processing routes, and reinforcement. Various ceramic particles (oxides, carbides, nitrides, borides, etc.) are used as reinforcements for aluminium matrix composites. Significantly different properties may be obtained using various reinforced particles and matrix material, which makes it difficult for the traditional fusion welding techniques to meet the joining requirements of these composites and is restricted to certain grades of materials. Solid-state welding process offers greater advantages over the conventional fusion welding. As a solid-state joining process, friction stir welding has proven to be a better and promising technique for joining aluminium matrix composites. However, it is still subjected to various challenges to join aluminium matrix composites even with considerable progress has been made in recent years. The current review provides an overview of state-of-the-art of friction stir welding of aluminium matrix composite materials. Specific attention and critical assessment have been given to weldability, the macrostructure and microstructure of aluminium matrix composite joints, mechanical properties of joints, fractography, and the wear of friction stir welding tool during welding of aluminium matrix composite. Furthermore, the various existing challenges of friction stir welding of aluminium matrix composites are summarized and the recommendations for future research are proposed.

Abstract:
The excellent mechanical properties of Aluminium Metal Matrix Composites find applications in a variety of engineering applications in the automotive, aerospace and heavy machinery industries. This study aims at synthesis and characterization of Al 64430 reinforced with SiC particles and Rice Husk Ash (RHA). Rice husk ash is an agricultural waste which is produced in millions of tons worldwide. Aluminium was used as the base metal. With liquid metallurgy technique the metal matrix composites were prepared. The MMCs were synthesized with 3 % weight percentage RHA in Al metal matrix and the mechanical properties such as hardness, tensile strength and structural properties of MMCs were studied. The microstructure of the synthesized composites was examined by optical emission microscope and XRD. The Vicker’s microhardness test was performed on the composite specimens from base of the cast. The synthesized MMCs were found to have increased tensile strength, hardness, increased ultimate strength. The density of MMCs was observed to be decreased. This study indicates that RHA can be used as reinforcement material to synthesize light weight composites with increased hardness, tensile strength, Young’s modulus for various industrial applications.

Abstract:
Metal matrix composites based on aluminium reinforced natural waste are a well-known material industry application because they can reduce environmental pollution. This paper presents the hardness and microstructure analysis of recycling milled aluminium (AA7075) at various composition of rice husk silica. Recycling milled AA7075 reinforced with rice husk burned at 1000°C at various composition i.e., 2.5, 5, 7.5, 10 and 12.5 wt.%, were investigated. Metal matrix composites samples were prepared by cold compaction method due to the lower energies consumption and operating cost compared to conventional recycling by casting. The results reveals that the hardness of metal matrix composites samples increased at increasing of rice husk silica up to 5 wt.%. The addition of rice husk silica increased the irregularities of pore shape and it resulted in higher porosity and random pore shapes compared to unreinforced metal matrix composites samples. Based on investigation of metal matrix composites samples, rice husk silica has good potential to improve the material behavior with appropriate composition of rice husk silica to metal matrix composite.

Abstract:
Hybrid metal matrix composites are new invention in material science and Engineering. The hybrid metal matrix composites (Hybrid MMC’s) generally consist of two or more reinforcements in it. These hybrid MMC’s have several benefits over the single reinforcement. The presence of reinforcements in it exhibits improved mechanical, tribological and machinability properties. Aluminium-based MMC’s have made attention in recent years as engineering materials. But in some Aluminium-based MMC’s the use of single reinforcement may sometimes lead to weakening in its physical properties. Conversely, to overcome the problem of single reinforced composites, the idea of the use of two different types of reinforcements is being explored in the Aluminium matrix. In the hybrid MMC’s, generally one of the reinforcements will be a hard phase and the other reinforcement being a soft lubricating phase. Hard reinforcements such as TiO2, Al2O3, SiC, etc. will improve the hardness and abrasive wear resistance of Aluminium but it has a negative effect on the machinability of Aluminium. To balance these effects, reinforcements like graphite which is a solid lubricant can be dispersed in Aluminium along with hard reinforcements. In the present study, the paper reviews on the effect of processing techniques, effect of reinforcement and effect of machining parameters on the machinability of hybrid aluminium metal matrix composites.

Abstract:
The present paper reports the effect of aluminium oxide and titanium oxide reinforcement on the properties of aluminium matrix. Aluminium matrix reinforced with aluminium oxide–titanium oxide (2.5, 5.0, 7.5 and 10 wt.%) in equal proportion were prepared by stir casting. Phase, microstructure, energy dispersive spectroscopy, density, hardness, impact strength and tensile strength of prepared samples have been investigated. X-ray diffraction reports the intermediate phase formation between the matrix and reinforcement phases due to interfacial bonding between them. Scanning electron microscopy shows that aluminium matrix has uniform distribution of reinforcement particle i.e. aluminium oxide and titanium oxide. Density of composite decreases due to variation of reinforcement and it shows low density after preheating. Hardness decreases due to the amalgamation of reinforcements. Impact strength was found to increase with the addition of reinforcements. Hybrid composite of aluminium matrix and (5% aluminium oxide + 5% titanium oxide) reinforcements have maximum engineering and true ultimate tensile strength. It is expected that the present hybrid metal matrix composites will be useful for aircraft rivets.

The thermal characteristics of the in-situ reaction were studied by differential scanning calorimetry (DSC). Field Emission Scanning Electron Microscopy (FESEM) along with the Energy Dispersive Spectroscopy (EDS) and X-ray diffraction (XRD) techniques were used to study the microstructural architecture of the composites as a function of SPS temperature and the volume fraction of reinforcement.

The aluminium is used for variety of reasons and they are known for their improved strength, stiffness, wear resistance which are useful in the marine, space, transport, automobile related industries. When aluminium reinforced with ceramic materials like fly ash, silicon carbide, tungsten carbide, boron carbide, fired bricks then a composite of better plastic forming capability, excellent heat and wear resistance will be formed. The objective of the experiment is to assess the thermal and mechanical properties of the Aluminium Metal Matrix Composites (AMMCs) when reinforced with ceramics. Aluminium (Al-7475) based metal matrix composites reinforced with varying weight percentage of Graphite(Gr) (3%, 6%, 9% and 12%) and fly ash being constant (10wt%) by the stir casting process. The composites tensile strength and hardness improved with the amount of graphite content improved in weight percentage up to 9% then decreased. While the composite’s Thermal Conductivity(TC) and Coefficient of Thermal Expansion(CTE) varying temperature range from 50°Cto 300°C reduces with increase in weight percentage of the graphite content.

In recent years, many alloys as well as composites of aluminium were developed for enhanced material performance. AA 6061 is an aluminium alloy that has extensive applications due to its superior material characteristics. It is a popular choice of matrix for aluminium matrix composite (AMC) fabrication. This study provides a review on AA 6061 aluminium alloy matrix composites produced through the stir-casting process. It focusses on conventional stir-casting fabrication, process parameters, various reinforcements used, and the mechanical properties of the AA 6061 composites. Several research studies indicated that the stir-casting method is widely used and suitable for fabricating AA 6061 composites with reinforcements such as SiC, B4C, Al2O3, TiC, as well as other inorganic, organic, hybrid, and nanomaterials. The majority of the studies showed that an increase in the reinforcement content enhanced the mechanical and tribological properties of the composites. Furthermore, hybrid composites showed better material properties than single reinforcement composites. The usage of industrial and agricultural residues in hybrid composites is also reported. Future studies could focus on the fabrication of AA 6061 nanocomposites through stir casting and their material characterisation, since they have great potential as advanced materials.
