Abstract:
A series of metal-matrix composites were formed by extrusion freeform fabrication of a sinterable aluminum alloy in combination with silicon carbide particles and whiskers, carbon fibers, alumina particles, and hollow flyash cenospheres. Silicon carbide particles were most successful in that the composites retained high density with up to 20 vol% of reinforcement and the strength approximately doubles over the strength of the metal matrix alone. Comparison with simple models suggests that this unexpectedly high degree of reinforcement can be attributed to the concentration of small silicon carbide particles around the larger metal powder. This fabrication method also allows composites to be formed with hollow spheres that cannot be formed by other powder or melt methods.

Abstract:
Mechanical characteristic of silicon carbide particle reinforced aluminum matrix composites produced by semi solid stir casting technique was investigated. Al7Si and Al7SiMg were used as metal matrix. High purity silicon carbida with average particle size mesh 400 was used as reinforcement particle. Aluminum matrix composites with variation of SiC: 5 %, 7.5 % and 10 % wt were manufactured by the semi solid stir casting technique. Stiring process was performed by 45 ° degree carbide impeller at rotation of 600 rpm and temperature of 570 °C for 15 minutes. Characteritation of composites speciment were: microscopic examination, density, hardness, tensile and impact test. Hardness and density were tested randomly at top, midlle and bottom of composites product. Based on distribution of density, distribution of hardness and SEM photomicrograph, it can be concluded that semisolid stir casting produces the uniform distribution of particles in the matrix alloy. The results also indicate that introducing SiC reinforcement in aluminum matrix increases the hardness of Al7Si composite and Al7SiMg composite. Calculated porosities increases with increasing wt % of SiC reinforcements in composite. The addition of 1 % Mg also increases the hardness of composites, reduces porosities of composite and enhances the mechanical properties of composites.

Abstract:
Tribological properties of silicon carbide-based aluminum metal matrix composite and aluminum matrix alloy have been studied for various sliding speeds of 3.14 and 3.77 m/s and load range from 10 to 30 N under dry, lubricated, and inert gas (argon) environment. Pin-on-disk tribometer were used for experiments. The composite was fabricated by stir casting route by using aluminum 7075 alloy as the matrix and 10% by weight silicon carbide as reinforced material. Results have revealed that the value of coefficient of friction is found to be maximum in case of inert condition in matrix alloy at sliding speed 3.77 m/s and minimum in case of lubricated condition in composite at sliding speed 3.14 m/s. The wear rate is least for both the alloy and the composite under lubricated condition compared with dry and inert condition. Wear rate increases with the normal load and sliding speed and it is maximum in inert condition of matrix alloy at 30 N. Uniform distribution of silicon carbide in aluminum matrix alloy reduces the values of coefficient of friction and wear rate for composites compared to aluminum matrix alloy under dry, lubricated, and inert condition which increases the life of the composites for longer duration. Silicon carbide significantly improves the strength the aluminum matrix alloy in dry, lubricated, and inert condition and acts as load-bearing members.

Abstract:
Aluminum carbide was found to form catalytically at aluminum-silicon carbide interfaces upon exposure to water vapor. Samples, composed of approximately 2 nm thick layers of Al on SiC, were fabricated and reacted in vacuo, and analyzed using XPS. Enhanced carbide formation was detected in samples exposed to 500 Langmuirs H2O and subsequently reacted for 600 s at 873 K. The cause of the catalysis phenomenon is hypothesized to be the weakening of silicon-carbon bonds caused by very strong bonding of oxygen atoms to the silicon carbide surface. Aluminum carbide formation is of interest because of its degrading effect on the mechanical properties of aluminum/silicone carbide reinforced metal matrix composites, as well as its effect on the electrical properties of aluminum metallizations on silicon carbide layers in microelectronic components.

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.

Abstract:
The sliding wear of an aluminum matrix composite, reinforced with different volume fraction of particles, against a stainless-steel slider has been studied. In dry conditions, i.e., unlubricated tests, the pairs (slider and specimen), wear. When rubbing against an aluminum alloy (unreinforced), the slider does not wear but the aluminum alloy wears quickly by adhesion. In dry conditions, both slider and composite wear, but there is a minimum wear rate for this pair at a critical volume fraction of reinforcing particles. Under lubricated conditions, the situation changes dramatically. The composite no longer wears, but the slider wears very quickly. Under water, results are a compromise between the two previous situations, dry and lubricated. These results are explained by a simple, descriptive mechanism, which takes in account both the effect of the shear rate, due to the sliding action in the composite, and the abrasive effect of the particles. A general relationship, which describes the effect of the applied pressure and volume fraction of particles in the composite, is proposed.

Material world requires a strong research to produce a new class of materials having light weight, higher strength and better performances. This has been leads to investigate for high strength light weight alloy. The main objective in developing aluminium metal matrix composites is to provide enhanced characteristic performances and properties above the currently available materials. Based upon the literature a new type of aluminium composite has been tries to develop which will offer attractive mechanical properties such as high strength, easy machinability, appreciable density, and low manufacturing cost etc. Aluminum powders of 99.55% purity and 325 mesh sizes are mixed with alloying metals like Copper, Magnesium, Silicon and Silicon Carbide powders in a precisely controlled quantity. During the process of powder metallurgy (P/M) product preparation, it was minutely observed to attain the maximum efficiency and accuracy. Aluminium (Al) is a light weight material but doesn’t possess a good strength. To achieve this, Copper (Cu), Silicon (Si), Magnesium (Mg) & Silicon Carbide (SiC) powders were blended with it at required proportions. The compaction was carried out with help of a C-45 steel die by power compaction press with a load of 150KN to 250KN. The obtained green products were sintered in a Muffle furnace to produce the final Aluminium Metal Matrix Composites (AMMCs) product.

Abstract:
Weldability of aluminum-based metal matrix composite A359/SiC/10p using gas tungsten arc welding and R356.0 filler material is investigated. The welding current, welding speed, and preheat temperature affect the weld quality significantly. Finite element analysis is successfully applied to map the weldment temperature during preheating and welding. During mechanical testing of welded specimens, a crack propagates in the parent composite or in the weld, but not in the stronger zone between the weld and the parent material. The weld region contains reasonably uniform distribution of SiC particles due to high viscosity of the molten weld and its fast cooling rate. Proper control of heat input and addition of silicon-rich filler material hinder the interface reaction between aluminum matrix and the reinforcing SiC particles, and successfully suppresses the formation of harmful aluminum carbide flakes in the weld. The average tensile and flexural strengths of optimally welded specimens approach those of the parent composite while its ductility exceeds that of the parent material.

In this research, metal-matrix composites (MMCs) of aluminium-11.8% silicon alloy matrix reinforced with titanium carbides particulates were fabricated by the casting technique. Aluminium-11.8% silicon alloy is selected as the matrix material and titanium carbide as particulates are mixed in different weight percentages, 5%, 10%, 15% and 20%wt. The cylinder composite castings are made by pouring the composite mixture in copper permanent-molds. The microstructure and mechanical properties of these composite materials were investigated. The effects of reinforced materials on weight percentages addition of particulate on the particulate distribution in aluminium-11.8% silicon alloy composites and SEM observation of the fracture surfaces of tensile tested specimens were deliberate. Moreover, cylinder castings without particulate addition are made and compared with the result based on the properties and microstructural features. It is found that the microstructure and mechanical properties of composites significantly improved by the use of particle reinforced into aluminium alloy.

Abstract:
Friction and wear behavior of silicon carbide based aluminum metal matrix composite and aluminum matrix alloy have been studied for sliding speeds of 3.14 m/s and 3.77 m/s and load range from 10 N to 30 N under dry and lubricated environment, respectively. The experiments were performed on pin on disk tribometer (Make: DUCOM). The composite was fabricated by stir casting process and has several challenges like inferior bonds and interfacial reaction products which will deteriorate the mechanical and tribological properties. Therefore, addition of reactive metal like magnesium (Mg) should be done which will lead to reduced solidification shrinkage, lower tendency towards hot tearing, and faster process cycles. Results have revealed that the developed composites have lower coefficient of friction and wear rates when compared with aluminum matrix alloy under dry and lubricated environment. Experimental results show that under dry condition coefficient of friction of both the matrix alloy and the composite decreases with increase in load, whereas it increases with increase in sliding speeds; on the other hand wear rates of both aluminum matrix alloy and the composites increase with increase in load as well as with sliding speeds. FESEM of worn surfaces are also used to understand the wear mechanisms.

Stir casting method is used in the production of SiC reinforced-aluminium metal matrix composite (AMMC) to enhance the properties of base metal. Different weight fraction of Silicon carbide, SiC (5 wt%, 10 wt% and 15 wt %) particulate-reinforced AMMCs are fabricated and characterizations of physical and mechanical properties of the materials are performed based on the experimental. The microstructure of the fabricated composite material are studied and analyzed. The results indicate that the mechanical properties of the composite, including yield strength, tensile strength and hardness are enhanced by the increment of the weight fraction of reinforcing phase. Nevertheless, the elongation and fracture toughness of the composite decreased as the reinforcing phase increased. This is mainly due to the brittleness of the SiC particles which act as micro void initiator.

Purpose The purpose of this paper is to determine the use of BLA along with SiC as economical reinforcements to enhance the mechanical behavior of hybrid composite. The purpose of this research is the development of cost-effective aluminum hybrid metal matrix composites. Design/methodology/approach The present research work investigation evaluated the mechanical properties of Al-4.5%Cu alloy, Al-4.5Cu/10SiC, Al-4.5Cu/10SiC/2BLA and Al-4.5Cu/10SiC/4BLA composites by the Stir casting method. The fabricated composites were analyzed using optical microscopy (OM), scanning electron microscopy (SEM), and hardness and tensile test. Findings The microstructure modification with the addition of reinforcement particles in the matrix alloy and clear interface in between matrix and particles are observed. The density of the composite increased with the addition of SiC and decreased with the addition of BLA in comparison with that of matrix alloy. The hardness and tensile strength of the single-reinforced composite and hybrid composites improved with the addition of reinforcement particles. The strengthening of composites was due to load-bearing capacity of reinforcement particles over the matrix alloy and increased dislocation density of composites materials. The tensile failure mechanism of the composites is reveled with SEM analysis. Practical implications The papers reports the development of cost-effective and light weight aluminum hybrid composites with remarkable enhancement in the mechanical and tribological properties with the addition of BLA as economical reinforcement along with SiC. Originality/value The density, hardness and tensile values of fabricated aluminium composites were presented in this paper for the use in the engineering applications where the weight and cost are consider as a primary factors.

Abstract:
Aluminum (Al) - Silicon Carbide (SiC) metal matrix composite is one of the widely used composites in today’s manufacturing industry. Al-SiC composites are produced through several methods such as casting and powder metallurgy, but its production through Reverse Two-Step Sintering (R-TSS) process in powder metallurgy has not been addressed so far. The present work focuses on manufacturing Al-SiC metal matrix composite through reverse two-step sintering process in powder metallurgy. The reinforcement element SiC is embedded with metal matrix element Al in different proportions. Then the consolidated mixture is compacted using the die and punch setup followed by a two-step sintering process suggested by Wong; thereby, the final compact is produced. Further, the processed sample is analyzed for density and hardness tests.

Abstract:
Nondestructive eddy current methods were used to evaluate the electrical conductivity behavior of silicon-carbide particulate (SiCp) reinforced aluminum (Al) metal-matrix composite extrusions. The composites investigated included 2124, 6061, and 7091 Al base alloys reinforced by SiCp. The composite extrusions exhibited anisotropic conductivities with the maximum conductivity occurring along the extrusion plane. Microstructural characterization showed that the observed anisotropic conductivities could result from the preferred orientation distribution of SiCp. A theoretical model was formulated to quantify the influence of composite constituents (SiCp, intermetallics, and Al base alloy) on the anisotropic conductivities of the composites. The theoretical predictions of conductivities were found to be in good agreement with the experimental results.

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.

Abstract:
This work deals with studying the effect of reinforcing SiC particles on the mechanical and plastic properties of a metal matrix composite with a matrix of aluminum alloy AlMg6 (the 1560 aluminum alloy according to the Russian State Standard GOST 4784−97). We assess this effect using the results of mechanical tests at the microscale and macroscale levels. The paper analyzes the fracture mechanism at the microlevel under tensile and compressive stress conditions, as well as the type of contact between the composite constituents. The experimental results obtained for the metal matrix composite are compared with analogous experimental data for the AlMg6 alloy and a compacted material made from the AlMg6 alloy (a compacted powder without addition of SiC reinforcing particles). The studied compacted materials were not previously subjected to extrusion. The tests show a decisive influence of the reinforcing particles on the plastic and mechanical properties of the AlMg6/10% SiC metal matrix composite under compression and tension. For example, the addition of silicon carbide increased the initial yield stress of the compacted material by 26% under tensile tests, and the percentage elongation after fracture was increased up to 1.1%, while it amounted to 0.02% for the compacted material without addition of silicon carbide. Under compression, on the contrary, the addition of silicon carbide degraded plastic properties. As a result, the percentage compression before cracking was 28.4% and 57.9% for the compacted materials with and without addition of silicon carbide, respectively.

AbstractAluminum is a light metal and is widely used in a variety of industries. Aluminum-silicon has good casting properties but does not offer any suitable tribological properties. Therefore, in this study surface composite coating was performed by the gas tungsten arc welding (GTAW) process, which increased hardness up to 34 HV, which is nearly two times compared to untreated specimens. This process is done by composite manufacturing with the silicon carbide reinforcement particles in the matrix of eutectic aluminum-silicon alloy. The mixed powder is deposited on the surface during melting by travelling the arc of GTAW. The desired optimum performance condition is achieved by arc current 75 amp, 1 g of poly vinyl alcohol (PVA) binder, 65 wt.% of aluminum powder and 15 wt.% of silicon carbide.

Abstract:
This work aims to investigate the effect of the addition of silicon carbide particles on the microstructure and the hardness of the Al-SiC metal matrix composites. The said composite is prepared using the stir casting technique for different weight percentages of the SiC particles. The higher composition of the reinforcement causes the clustering of the particles in the matrix. Thus, research has to be carried out on the aluminum-silicon carbide composites with the reinforcement 3wt%, 6wt%, 9wt%, and 12wt% of SiC particles to obtain the optimized composition. In order to study the microstructure and the reinforcement distribution in the matrix, a scanning electron microscope is utilized. The hardness testing has been carried out using the Vickers’ indentation technique for the as-cast and age hardening conditions. From the microstructural study, it is observed that the microstructure of the said composite exhibits the uniform distribution of the reinforcement. The EDX results show the presence of the reinforcing elements in the Al-SiC composite. From the results obtained from the hardness testing, it is observed that the presence of the carbide element in the composite increases the hardness of the Al-SiC particulate composites.

Abstract:
Self-lubricating materials are usually multi-phase composites comprising of a solid lubricant dispersed in a matrix of a metal or a polymer. During sliding contact, chemical reactions among the constituent phases of the composite, the counterface and the gases in the surrounding environment are inevitable. The wear debris is a product of such chemical (or tribochemical) reactions. Determination of the chemistry and the crystal structure of the wear debris is therefore crucial to the understanding of the wear mechanisms. In self-lubricating composites, the quantity of the debris generated is often too small to perform x-ray diffraction.It has been previously demonstrated that self-lubricating aluminum metal-matrix composites can be synthesized by dispersing silicon carbide and tungsten disulfide particles in commercial aluminum alloy matrices. A typical microstructure of an Al-0.10SiC-0.05WS2 MMC is shown in Fig. 1. The friction and wear test was performed, in a ball-on-disk configuration, on a polished disk of the aluminum MMC against a 440C steel ball.

Metal matrix composites are of interest every day due to their lightweight, improved mechanical properties, and increased corrosion resistance. They are used in the aeronautical, aerospace, marine, and automotive industries. A variety of methods can estimate Their corrosion properties. The open-circuit potential studies are also a tool for evaluating the corrosion of composite materials. This research paper focuses on studying open circuit potential determination of the aluminium 7075 alloys reinforced with silicon carbide particulate in differently concentrated sodium hydroxide solutions. The composite materials were prepared by adding 2, 4, 6, 8 and 10 weight percentages of silicon carbide to the aluminium base metal liquid melt metallurgy technique (Vortex method). The silicon carbide used as reinforcement in size range of 50 – 80 µm, which is commercially available. The SiC particulates material is had been preheated to 400°C and introduced into the liquid melt of Al7075 at a rate of 100 g/m, under constant agitating condition using a mechanical stirrer system for 3 to 4 minutes. Rectangular specimens of 2 cm length, 1cm width and 1 mm thickness were used for the experiments. 1sq.cm area of the specimens was exposed to sodium hydroxide medium. Open circuit potential experiments test was conducted using a multimeter and calomel electrode system. The potential observed for 2, 4, 6, 8 and 10% silicon carbide composites were less than the potential of matrix alloy for a range of 30 hours.

Boron carbide /aluminum composites have been produced on an aluminum–silicon cast alloy using friction stir processing. Effect of pin profile on the distribution of boron carbide in the stir zone of the friction stir processed specimens was investigated experimentally and numerically. The material flow generated by the threaded and circular tool pin profiles, being the main reason for the distribution of particles in the metal matrix, was numerically modeled using a thermomechanically coupled three-dimensional finite element model. Numerical and experimental results show that threaded pin profile produces a more uniform distribution of B4Cp than other pin profiles. Hardness tests were performed in order to investigate mechanical properties of the composites. Wear resistance of the composite was evaluated and obtained results showed that the hardness and wear resistance of the composite significantly improved.

Abstract:
The demand for aluminum hybrid metal matrix composites has increased in recent times due to their enhanced mechanical properties for satisfying the requirements of advanced engineering applications. The performance of these materials is greatly influenced by the selection of an appropriate combination of reinforcement materials. The reinforcement materials include carbides, nitrides, and oxides. The ceramic particles, such as silicon carbide and aluminum oxide, are the most widely used reinforcement materials for preparing these composites. In this paper, an attempt has been made to prepare an Al6061 hybrid metal matrix composite (HAMMC) reinforced with particulates with different weight fractions of SiC and Al2O3 and a constant weight fraction (5%) of fly ash by a stir-casting process. The experimental study has been carried out on the prepared composite to investigate the mechanical properties due to the addition of multiple reinforcement materials. The density and mechanical properties, such as ultimate tensile strength, yield strength, impact strength, and the hardness and wear characteristics of the proposed composite, are compared with those of unreinforced Al6061. The experimental investigation is also aimed at observing the variation of properties with a varying weight percentage of the reinforcement materials SiC and Al2O3 simultaneously with the fly ash content maintained constant. The outcome of the experimental investigation revealed that the proposed hybrid composite with 20% of total reinforcement material exhibits high hardness, high yield strength, and low wear rate but no considerable improvement in impact strength.
