Abstract:
The increasing concern for sustainable materials and waste management has led to innovative approaches in material science. This study explores the potential benefit of aggregate waste in the production of aluminum composites practicing powder metallurgy techniques. The aim is to investigate the feasibility of incorporating bone material into aluminium matrices to enhance the composite’s mechanical properties. The research involves several key steps. Firstly, waste bone material is collected and processed to obtain a fine powder suitable for powder metallurgy. Various techniques such as grinding, milling, or pulverization are employed to achieve the desired particle size distribution. Next, the bone powder is mixed with aluminium powder in predetermined ratios to create composite blends. The composite blends are then subjected to compaction using powder metallurgy techniques, including cold pressing and sintering. The compaction process aims to consolidate the powders and facilitate the formation of a solid composite structure. The aluminum composites mechanical characteristics are then assessed. The effects of incorporating bone material are assessed using tests on tensile strength, ductility, hardness, and other relevant mechanical properties. Comparative analysis is performed between the composites with bone material and traditional aluminium composites to assess any improvements or changes in performance.

Abstract:
Although many problems in aluminium matrix composites have been solved, there are still many difficulties and challenges that need to be solved. In this work, graphene reinforced aluminum matrix composites are prepared by hot isostatic pressing and vacuum sintering. The microstructures of composite powders and composites were studied by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The effects of different ball milling parameters on the microstructures of composite powders were analyzed. The particle size of graphene coated aluminium composite powder increases with the increase of ball-to-material ratio. With the increase of milling time, graphene was gradually dispersed and coated on the aluminium powder particles, and the aluminium powder particles could be completely coated. with the increase of the speed, the large particles are extruded, sheared and the particles become smaller. The internal micro-deformation characteristics of graphene reinforced aluminium matrix composites were analyzed in detail.

Abstract:
The performances of aluminum /vinylester particulate-composites were studied in detail in order to investigate its suitability for engineering applications. This study examined the suitability of atomised aluminum particles for particulate reinforcement of a vinyl ester resin. Mechanical properties were obtained for the composite by testing various percentages of aluminium powder (75-150 m) and vinylester resin. It has been found that the inclusion of Al powder has not significantly changed the properties of vinylester resin, however an improvement in the ductility of the composite has been recorded. The optimal performances of the composite were exhibited by 15% Al composition. The properties of the particulate composites were modeled using numerous empirical models. Unfortunately a significant difference was found between some of the experimental and predicted properties of the Al/vinylester particulate composite. This paper intends to detail the variation of mechanical properties with the change of Al volume fraction in the composite and the performances of empirical models in prediction of the properties of particulate composites.

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:
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:
Aluminium matrix composites offer improved damping properties than other metals and its alloy. Generally pure metals and its alloys may have fairly good mechanical properties but falls short in damping properties. Aluminium matrix composites are becoming important in aerospace automobile and marine applications due to its god damping properties. The present investigation is concerned with the damping capacity of iron oxide (Fe2O3) reinforced aluminium matrix composite. The composites were fabricated with 2%, 4% and 6%, by weight of iron oxide with varied particle of size 40 μm and 500 nm in equal proportions using stir casting process. From the results obtained the 500 nm size with 4 wt% of iron oxide showed improved dynamic properties. The iron oxides reinforced with aluminum matrix are found to be new substitutes for the existing materials with low damping properties.

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:
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:
La plupart des composites à matrice métalliques étudiés à l'heure actuelle sont élaborés par trois technologies principales, dont le coût relativement élevé limite les domaines d'utilisation. Pour palier cet inconvénient, nous avons travaillé à mettre au point un procédé de cofilage en phase solide. L’évolution du procédé nous a permis de résoudre les problèmes d'imprégnation du renfort par la matrice. Dans le cadre de l'optimisation des étapes de fabrication, nous avons étudié l'influence des paramètres suivants sur le comportement et les mécanismes d'endommagement du matériau: longueur des fibres, orientation du renfort et fraction volumique locale. Pour cela nous avons développé une démarche de type micro-macro fondée sur la théorie d'inclusion équivalente d'Eshelby. Nous modélisons ainsi l'influence de la microstructure sur les caractéristiques élastiques, les coefficients de dilatation et la surface seuil d'écoulement. Des calculs par éléments finis sur cellules de base à trois phases complète cette approche. Nous regardons l'influence de la répartition des fibres sur le développement de la plasticité locale. Une configuration de fibres proches de leurs voisines a un rôle prépondérant sur la propagation de l'endommagement qui se produit en tête de fibre. Nous proposons un critère analytique d'initiation de cet endommagement qui prend en compte la distribution de fraction volumique locale dans le matériau. Les résultats sont comparés à des essais de traction dans l'enceinte du microscope électronique à balayage, ou nous pouvons suivre les différentes étapes du processus de rupture. L’outil analytique développé est intégré dans une démarche originale de détermination d'une statistique d'endommagement pour une structure. Nous pouvons, ainsi, donner localement la probabilité d'endommagement d'un volume de composite en fonction de l'observation de ses distributions de microstructure, et du chargement

Abstract:
L'objectif de l'étude est d'apporter une contribution à la compréhension des phénomènes interfaciaux qui interviennent lors de l'élaboration des matériaux composites à renfort fibreux et à matrice aluminium. Les renforts choisis pour cette étude ont été des fibres de carbone, des fibres de carbone protégées, et des fibres à base de carbure de silicium. Ces fibres sous forme de tissu ont été recouvertes d'aluminium par dépôt physique en phase vapeur. Les matériaux ainsi obtenus ont subi des traitements thermiques dans un réacteur couple à un spectromètre de masse. L'existence de réactions entre certains gaz produits par les fibres (CO, CO2) et l'aluminium lorsque la température est supérieure à 650°C a ainsi pu être mise en évidence. Ces réactions se produisent lors de la traversée du dépôt d'aluminium par les gaz issus des fibres et provoquent la formation de carbone d'aluminium. Le carbure d'aluminium est également formé par des réactions entre les espèces solides constituant les fibres et le métal. La quantité de carbure d'aluminium formé à l'interface fibre/métal lors des traitements thermiques a été déterminée par hydrolyse. Il a ainsi pu être montré que le carbure d'aluminium provient essentiellement des réactions entre les solides constituant les fibres et le métal. L'efficacité de divers recouvrements contre la formation de carbure d'aluminium a aussi été étudiée.

Abstract:
Les matériaux composites à matrice métallique (CMM) sont actuellement étudiés pour être utilisés dans de nombreux domaines d’application. L’une des applications potentielles concerne leur utilisation en tant que drain thermique pour les modules de puissance. Pour cette application, deux conditions sont requises : une conductivité thermique (CT) élevée pour évacuer la chaleur générée par la puce électronique et un coefficient d’expansion thermique (CTE) proche du substrat céramique (2-8×10-6 /K) utilisé dans le module de puissance.Ainsi des matériaux composites à matrice aluminium (Al : CT de 217 W/m.K et CTE de 24×10-6 /K) et à renfort plaquette de graphite (GF : CT de 1000 W/m.K et CTE de -1×10-6 /K dans le plan de la plaquette) ont été élaborés. Ces matériaux composites ont été fabriqués par Métallurgie des Poudres (MP) conventionnelle mais aussi par un procédé original nommé Flake Powder Metallurgy (FPM). Ce procédé, qui consiste à utiliser une poudre métallique à morphologie plaquette, a permis d’optimiser l’orientation des renforts plaquette dans un plan perpendiculaire à la direction de densification sous l’action d’une pression uniaxiale. De plus, ce procédé a permis d’obtenir une meilleure adhésion entre la matrice et le renfort comparé aux matériaux composites élaborés par MP conventionnelle. Cela a abouti à une amélioration de la CT qui est passée de 400 W/m.K à 450 W/m.K pour un taux de renfort de 50%vol. Néanmoins, concernant la dilatation thermique, des CTE de 21,8×10-6 /K et 21,7×10-6 /K ont été obtenus par MP et FPM respectivement, ce qui est incompatible avec l’application visée.Pour surmonter cette problématique, des matériaux composites à renfort multiple ont été élaborés par frittage en phase liquide. Ainsi des fibres de carbone (FC) ont été rajoutées à l’aluminium et aux plaquettes de graphite. L’ajout de ce second renfort au graphite a permis de diminuer de manière importante le CTE des composites Al/(GF+FC) avec une faible proportion en FC tout en maintenant une haute CT. De plus les matériaux composites Al/(GF+FC) présentent des CTE nettement inférieurs aux composites Al/FC avec un %vol. de FC équivalent. Ainsi des matériaux composites Al/(GF+FC) ont été élaborés par frittage en phase liquide permettant d’obtenir une CT de 400 W/m.K (comparable à la CT du cuivre) et un CTE de 8×10-6 /K (comparable au CTE de l’alumine). De plus la légèreté de l’aluminium confère aux matériaux composites Al/C une faible densité (d=2,4). Par conséquent, les matériaux développés dans cette étude sont prometteur en tant que drain thermique léger, notamment dans le domaine de l’électronique embarquée
Many carbon/metal composites are currently used in several applications. One of them concerns their use as heat sinks in microelectronics. Concerning this application, two conditions are required: a high thermal conductivity (TC) in order to evacuate the heat generated by the electronic chip and a coefficient of thermal expansion (CTE) similar to the used material type of the electronic device (2-8×10-6 /K).Therefore, graphite flakes (GF; TC: 1000 W/m.K and CTE: -1×10-6 /K in the graphite plane) reinforced aluminum matrix (Al; TC: 217 W/m.K and CTE: 25×10-6 /K) composites were fabricated. These composite materials were fabricated by Powder Metallurgy (PM) and Flake Powder Metallurgy (FPM). This process, which consist to use a flattened metallic powder, helped to improve the in-plane orientation (perpendicular to the pressure direction) of GF under uniaxial pressure. Moreover, this process provided a better Al-C interface thanks to a planar contact between the matrix and the reinforcements. This resulted in an improvement of the CT from 400 W/m.K to 450 W/m.K for a reinforcement content of 50 vol.%. Nevertheless, regarding thermal dilation, CTEs of 21.8×10-6 /K and 21.7×10-6 /K were obtained by MP and FPM respectively, which is incompatible with the intended application.To overcome this problem, composite materials with multiple reinforcement were developed by solid-liquid phase sintering. Then, carbon fibers (CF) have been added to aluminum and graphite flakes. The addition of CF to GF reinforcement reduced significantly the CTE of the Al/(GF+CF) composites with a small proportion of CF, while preserving a high TC. In addition, the Al/(GF+FC) composite materials have significantly lower CTEs than the Al/CF composites with a equivalent vol.% of CF. Therefore, Al/(GF+CF) composite materials were developed by solid-liquid phase sintering to obtain a TC of 400 W/m.K (comparable to the TC of copper) and a CTE of 8×10-6 /K (comparable to the CTE of alumina). In addition, the lightweight of aluminum gives composite materials Al/C a low density (d = 2.4 g/cm3). Therefore, the composite materials developed in this study are promising as a lightweight heat sink in microelectronic industries

Abstract:
Friction stir welding (FSW) is an upgraded version of the conventional friction welding process, and it is considered the latest development and the most important one during the past two decades in the welding of metals. The dependence of FSW on friction and plastic work as a heat source precludes the melting in the workpiece and leads to avoiding many of the difficulties arising from the change in the state of the material, such as defects, distortion and residual stresses, which often happen in conventional welding processes. FSW gained significant attention as a solid-state welding process of aluminium alloys, but now there is a need to extend its application to advanced materials such as metal matrix composites (MMCs). However, the process has always represented a challenge owing to the complexity of microstructural development and the associated number of process parameters to take into consideration. This thesis investigates the feasibility of welding two new advanced aluminium matrix composites (AMCs), AA 6092/SiC/17.5p-T6 and AA 6061B/SiC/20p-T1 by FSW for the first time. Also, aluminium alloy AA6082-T6 has been investigated as base-line material to specify the benefit, drawback, and FSW window. Experiment analyses were conducted to evaluate the influence of FSW parameters, including tool rotation and traverse speeds on the quality of weldments. Weld joints were characterised in terms of thermal history, metallurgical behaviour, mechanical properties, and residual stresses. The metallurgical characterisations have been done by optical, scanning electron microscopy (SEM), electron backscattered diffraction (EBSD), transmission electron microscopy (TEM), and energy dispersive X-ray spectroscopy (EDS). Microhardness, tensile, and low-cycle fatigue (LCF) test with the axial total strain-amplitude control mode R=ε_min⁄(ε_max=-1) were used for evaluating the mechanical properties. The results showed that the generated peak temperature in the welding joints is affected more significantly by the rotating tool speed, while the exposure time and subsequent cooling rate are controlled by tool traverse speed. The microstructure of nugget zone (NZ) exhibits an elliptical shape with a substantial grain refinement resulted from continuous dynamic recrystallisation (CDR) process with an increase in the fraction of high angle grain boundaries (HAGBs). The evolved grain size was greatly influenced by weld pitch as the ratio between tool traverse speed to tool rotation speed, which is a key parameter to control the amount of heat input, exposure time and cooling rate. In addition, in the case of AMCs more homogeneous distribution of reinforcement particles (SiC) coupled with particle refinement were formed in the NZ. The cross-weld microhardness profile revealed a significant difference in microhardness among the base metals, heat affected zone (HAZ), thermo-mechanically affected zone (TMAZ), and NZ in the case of AA 6082 and AMC (AA 6092/SiC/17.5p), as they depend on the strengthening precipitate. Meanwhile, the hardness profile of AMC (AA 6061B/SiC/20p) FSW joints showed that there is no difference in the measured hardness between the welding zone and base materials because the welded joints are exposed to thermal history similar to the initial heat treatment condition of the base metal, T1, cooled from an elevated temperature shaping process and naturally aged. The tensile strength of AA6082, and AMC (AA 6092/SiC/17.5p) cross-weld FSW specimens was found to be lower than their base metals with a joint efficiency (the ratio of the tensile strength of joint to the tensile strength of base metal) of about 71 and 75 %, respectively. While for SAMC (AA 6061B/SiC/20p) FSW joints it is reached 108 % of that of the base metal. The low-cycle fatigue results indicate that the fatigue life of the cross-weld joints varies with grain size in the NZ, and it is always lower than that of the base metal. A significant improvement in fatigue life is found to be related to the finer equiaxed grains dominated by HAGBs in the NZ, as well as, to less gradient in the grain size of the cross-weld. Residual stresses are significant concerns associated with the welding process, as it can combine with applied stresses, which may lead to the reduction of structural properties. The result of residual stress measurement by neutron diffraction techniques exhibited a typical ''M'' profile, which indicates that compressive and tensile residual stress existed in the base metal and welding zone, respectively. This has not only provided an improved understanding of residual stresses in FSW joints but also has contributed to the validation of 3D fully coupled thermo-mechanical finite element (FE) model, which has been developed based on Coupled Eulerian-Lagrangian (CEL) technique. The model is also used to predict the thermal history and material flow in the FSW of aluminium alloy AA6082. The numerical results showed a good agreement with the experimental results.

Abstract:
Metal matrix composites consisting of 6061 and 2014 aluminium alloys, reinforced with 10%, 15% and 20% alumina particulates and a 6061 alloy reinforced with 20% SiC particulates, have been characterised in terms of their behaviour under various tribological conditions. In abrasive environments, the wear behaviour of each composite is dominated by their ability to resist indentation by hard particles. Abrasion against fine grit particles leads to a reduced load per abrasive particle and a correspondingly significant reduction in wear loss. Reciprocating sliding wear tests, conducted in an aqueous environment and against hardened steel counterfaces, displayed composite wear rates that were up to three orders of magnitude below those of their monolithic alloys. This is attributed to the increased resistance to surface shear provided by the reinforcing particulates themselves and their constraining effects on the matrix. The particulates become load bearing and protect the matrix by reducing the metal to counterface adhesive wear. However, the counterface wear increases due to the interaction with the hard reinforcements. Transmission electron microscopy of the worn composites reveal the formation of a transfer layer and subsurface dislocation structures which are similar to those found in metals subjected to low amplitude fatigue. In contrast to the results for abrasive and sliding wear, the composites show increasingly inferior cavitation and solid particle erosion resistances with increasing volume fractions of particulates. This depreciating effect was especially evident for particle erosion and can be related to the inability of metal matrix composites to accommodate the increments of strain which accompany erosive processes. The mechanisms responsible for the various performances have been studied by scanning electron microscopy, optical microscopy and transmission electron microscopy. An attempt is made to reconcile the steady state wear rates of the reinforced and unreinforced alloys with their observed wear modes, microstructures and bulk mechanical behaviour.

Abstract:
Metal matrix composites (MMCs) constitute an important class of weight-efficient structural material which empowering every field of engineering applications. Aluminium based metal matrix composites contains potential for high specific strength and advanced structural applications, as well as good elevated temperature resistance along with light weight application. However, need for improved tribological performance has led to the fabrication of newer variants of the composite. In the present work, aluminium based metal matrix composite (MMCs) developed through stir casting route by reinforcing different weight percentage of SiC micro (5% and 10%) and nano (1% and 2%) particles. In this research, 5083 aluminium alloy is used as matrix phase due its broad range of industrial applications. Wear behaviour of the developed aluminium matrix composite (AMC) was investigated under different conditions of applied load, operation time and speed. The analysis carried out at room temperature for three different loads (10N, 20N, and 30N) with varying four different operation times (30 mins, 60 mins, 90 mins, and 120 mins). The speed was kept constant at 1450 rpm during all experiments. The results of all considered composites are investigated and the composite with 2% SiC nano reinforcement is identified as a superior among all other composition for tribological applications point of view. Also the developed aluminium matrix composites have potential applications in many industries such as pressure vessels, pipe fittings, boat hulls, gears and pistons.

Abstract:
Aluminium alloys are being widely used in naval applications owing to their excellent corrosion resistance and high formability characteristics. One of the most popular naval components is the tarpedo blade which makes use of forged aluminium alloy followed by anodizing surface treatment for corrosion protection. In recent years, there have been few attempts to replace the conventional aluminium alloys by their composites for the tarpedo blade applications. Literature review clearly says that CeO2 (Ceria) coating on aluminium and aluminium composites enhances their corrosion protection in aggressive marine environment. Further, there are reports suggesting that combination of CeO2 and TiO2 do yield better corrosion protection. However, there is no information on the work related to development of hybrid ceramic reinforced aluminium alloy matrices with CeO2 and TiO2 as particulate reinforcements for potential naval applications. In the light of above, the present work focuses on the development of novel Al6061-CeO2-TiO2 hybrid metal matrix composite by stir casting route followed by hot extrusion with an extrusion ratio of 8:1 at a temperature 550 °C and hot forging at 475 °C. The developed forged hybrid composites and the matrix alloy have been evaluated for microstructure, micro hardness and slurry erosion wear tests as per the ASTM Standards.

Abstract:
Vacuum co-evaporation of polymer materials and metals or their compounds allows the production of thin layers of specific properties. The method is technologically convenient and presents a certain alternative to the "sol-gel" technologies. Composite thin layers (1-1.5 μm) have been obtained by the simultaneous evaporation (10 A/sec) of two monomers (oxydiamline and pyromellitdianhydride) and a metal. As metal a thermally evaporated Al (0.6 A/sec) or an organometalic compound [(CH3)3NAlH3] have been used. The Al-organic compound is thermally decomposed during the first stage of imidization taking place at a temperature of 173 - 177 °C. Electron micrographs exhibit evenly distributed Al particles in the volume of the polyimide matrix with very small dispersivity values (2.5 - 5.0 nm - 90%). The second thermal stage od imidization (270 °C) does not cause coalescence of Al particles. It is assumed that a micro metal synthesis occurs by the build-up of strong C-O-Al bonds which fix the aluminium clusters. The optical parameters of the obtained composites have been measured at the various stages of the imidization process of the matrix. XeCl laser action (308 nm, 30 nsec, 30 to 4000 mJ/cm2) on the materials has been studied envisaging possibilities for micro-structuring. X-ray photoelectron spectroscopy in the exposure area shows a shift of Al2O3 (2.4 eV) which is higher than the Al photoelectron peak (1.7 eV). It is suggested that the laser action does not only break the imide bonds, but also stimulates the course of the chemical reaction on the particles' surfaces. Scanning micrographs demonstrate that the laser ablation process influences the average size of the Al particles.

Abstract:
Aluminium based metal matrix composites with nano particle reinforcement are currently finding wide spread applications in automobile, aerospace and space structures because of their high strength, fatigue life, excellent wear resistance, low thermal coefficient value. However, in order to use these materials for critical automotive applications, extensive study in terms of manufacturing feasibility of the composites have to be carried out. Based on the objectives, the present investigation focuses on the development of Aluminium-SiC nano composite for structural applications. The aim of this research work is to arrive at an optimum weight faction of nano particle which gives the highest properties of the nano composite. The composites were produced by stir casting route. The base alloy and the composites were extruded and subsequently subjected to age hardening treatment. Microstructural evaluation, hardness studies were carried out on both the base alloy and the composites in the as-cast and extruded conditions. The effect of extrusion on the microstructure and properties of the AA2014-0.8 wt.%SiC composites have been discussed in detail.

Abstract:
This report presents a review of quasi-static and dynamic properties of various iron, titanium, nickel, cobalt, and aluminum metals. The physical and mechanical properties of these materials are crucial for developing composite armoring systems vital for protecting critical bridges from terrorist attacks. When the wide range of properties these materials encompass is considered, it is possible to exploit the optimal properties of metal alloys though proper placement within the armoring system, governed by desired protective mechanism and environmental exposure conditions.
