Abstract:

The limitations of aluminium in most engineering applications has led to the development of aluminium matrix composites with improved microstructural and mechanical properties. Nanoindentation techniques was used in assessing the mechanical properties of fabricated aluminium matrix composites with ferrotitanium and silicon carbide as reinforcements. Results from nanoindentation experiments shows the dependence of modulus of elasticity, microhardness and contact depth on the dispersion of ferrotitanium and silicon carbide reinforcements within the aluminium matrix. Highest nanohardness value was observed in composite with 7 wt. % silicon carbide, while the lowest elastic modulus was recorded in as-cast aluminium. Further analysis of specimens confirmed a decrease in maximum penetration depth with respective increase in the addition of silicon carbide reinforcements in the fabricated composites.

Abstract:

The widely used Si3N4-SiC sidewall refractories for aluminum smelting cells, and β SiAlON-SiC composites that can be potentially used for this purpose, have been produced by reaction bonding and their corrosion performance assessed in simulated aluminum electrochemical cell conditions. The formation of the Si3N4 and SiAlON phases were studied by reaction bonding of silicon powders in a nitrogen atmosphere at low temperatures to promote the formation of silicon nitride, followed by a higher heating step to produce β SiAlON composites of different composition. The corrosion performance was studied in a laboratory scale aluminum electrolysis cell where samples were exposed to both liquid attack from molten salt bath and corrosive gas attack. The corrosion resistance of the samples was shown to be dependent on the composition but more importantly on the environment during corrosion, with samples in the gas phase showing higher corrosion.

Abstract:

Amongst the Metal Matrix Composites (MMCs), Al-Si-Mg alloy/ SiCp MMCs are very attractive for their properties. But, the formation of brittle interfacial reaction product, Aluminium carbide has been one of the major concerns when these materials are processed by liquid phase methods. The extent of Aluminium carbide formation depends on various processing parameters such as temperature, wt% of SiCp, particle size of SiCp and chemical composition of the matrix alloy especially Silicon (Si) content. According to recent studies, various difficulties in finding the process parameters to get desirable properties of Al alloy/ SiCp MMCs as desired by the industries. Thus, in the present study thermodynamic & structural estimates in Al alloy/ SiCp MMCs under various process conditions, composition, microstructures were performed. The relatively low cost liquid stir casting technique is used in the production of Al alloy/ SiCp MMCs with varying Silicon content (0–7%) in the alloy matrix using process temperature 710°C. Aluminium carbide layer formation on SiCp surface, Critical Si content for Aluminium carbide separation from SiCp surface, eutectic Si formation, existence of near-dislocation segregation regions after formation of Aluminium carbide on SiCp surface and the equilibrium amount of Si to suppress Aluminium carbide formation were investigated using Transmission electron microscopy (TEM). The separation of Aluminium carbide from SiCp surface was observed after 3% Si. The equilibrium Si content of 7% was found to suppress the formation of Aluminium carbide with thermodynamic model and its significance has been assessed.

Abstract:

Aluminium silicon carbide particulate composites have wide ranging applications in automobile, aerospace and military industries because of their attractive properties such as high strength-to weight ratio, high wear resistance, high temperature stability etc. From the machining point of view, these are one of the most difficult-to-machine materials, primarily due to the presence of SiC reinforcements causing an excessive wear of cutting tools during machining. On the other hand aluminium-graphite composites are widely used in tribological applications because of their excellent antifriction properties, wear resistance and antiseizure characteristics. Investigations have been carried out in this work to assess the machinability of aluminium matrix composites containing both SiC and graphite particulates as reinforcements. Turning experiments have been conducted on Aluminium-Graphite-Silicon Carbide hybrid composites using Carbide and PCD tool inserts to determine the flank wear. Experiments have been carried out based on Central Composite Design approach.

Abstract:

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:

Silicon carbides is a composite ceramic material produced from inorganic non-metallic substances, formed from the molten mass which solidifies on cooling and simultaneously matured by the action of heat. It is used in various applications such as grinding wheels, filtration of gases and water, absorption, catalyst supports, concentrated solar powers, thermoelectric conversion etc. The modern usage of silicon carbide is fabricated as a heat exchanger for high temperature applications. Leaving behind steel and aluminium, silicon carbide has an excellent temperature withstanding capability of 1425°C. It is resistant to corrosion and chemical erosion. Modern fusion reactors, Stirling cycle based gas turbines, evaporators in evaporative cooling system for air condition and generator in LiBr/H2O absorption chillers for air conditioning those systems heat transfer rate can be improved by replacing a present heat exchanger with silicon carbide heat exchanger. This review presents a detailed discussion about processing technique of such a silicon carbide. Modern known processing techniques are partial sintering, direct foaming, replica, sacrificial template and bonding techniques. The full potential of these materials can be achieved when properties are directed over specified application. While eyeing over full potential it is highly dependent on processing techniques.

Abstract:

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:

The paper is focused on the processing of aluminum alloy chips using powder metallurgy. Chips obtained from recycled AlSi5Cu2 alloy were ball milled with the addition of silicon carbide powder with an average size of 2μm. Mechanical alloying process was employed to obtain homogeneous composite powder. The effect of processing time (0 - 40h) on the homogeneity of the system was evaluated, as well as a detailed study of the microstructure of AlSi5Cu2 aluminum chips and SiC particles during MA was carried out. Addition of silicon carbide (10, 20wt%) to recycled aluminium chips and application of MA lead to fragmentation of the homogeneous composite powder down to particle size of about 3μm and spheroidization. The addition of hard SiC particles caused reinforcement and reduced the milling time. Higher content of silicon carbide and longer processing time allowed to obtain AlSi5Cu2/SiC powders with microhardness ∽500HV0,025. The results of MA were investigated with SEM, EDS, LOM, XRD and showed that relatively homogeneous distribution of SiC reinforcements in the matrix as well as grain refinement of aluminum solid solution down to 50nm can be obtained after 40h of processing.

Abstract:

Aluminium based composites exhibit many attractive material properties such as increased stiffness, wear resistance, specific strength and vibration damping and decreased co-efficient of thermal expansion compared with the conventional aluminium alloys. Aluminium Matrix Composites consist of non-metallic reinforcement which offers advantageous properties over base material. Reinforcements like SiC, B4C and Al2O3 are normally preferred to improve the mechanical properties. Here Aluminum LM25 is selected as matrix material while Silicon carbide and Boron carbide are selected as reinforcement material. The fabrication of aluminium matrix was done by stir casting method. In the present study an attempt has been made to investigate the effect of three major stir casting parameters (stir speed, stir duration and preheated temperature of reinforcement material) on stir casting of Aluminium LM25 - SiC - B4C composite. Experiments were conducted based on Taguchi methodology. Taguchi quality design concepts of L9 orthogonal array has been used to determine S/N ratio and through S/N ratio a set of optimum stir casting parameters were obtained. The experimental results confirmed the validity of Taguchi method for enhancing tensile strength of castings.

Experimental investigation of the aluminium based MMCs reinforced by silicon carbide of volume fraction equal to 0%, 10%, 20% and 30% were carried out. Tests were conducted at wide range of strain rates and large magnitudes of strains. Comparison between experimental and predicted data shows that the elaborated model may be applied for composite materials in computer simulations of large deformations.

Abstract:

This study was conducted to investigate the synthesis, characterization and mechanical properties of aluminium reinforced with ferrotitanium and silicon carbide via stir casting technique. Microstructures of as-cast samples were analysed using optical and scanning electron microscopes equipped with energy-dispersive X-ray spectroscopy. The mechanical properties in terms of hardness, tensile, tribological behaviour and fracture were assessed. Results showed that the homogeneous dispersion of reinforcement was within the metal matrix composite. Tribological study revealed a decrease in frictional coefficient of the composites with lowest frictional coefficient observed in composite with addition of silicon carbide as reinforcement. Morphology of fractured surface displayed a reduction in the size of dimples formed in reinforced aluminium composites when compared with larger dimple sizes observed in as-cast aluminium alloy.

Abstract:

Hybrid composite materials based on an aluminium phosphate matrix with silicon carbide whiskers and multi-walled carbon nanotubes were studied in a wide frequency range (20 Hz to 36 GHz). It was demonstrated, that the addition of the silicon carbide whiskers enhances the dielectric permittivity and conductivity. This was explained by the difference in tunnelling parameters. Hybrid ceramics with nanotubes and whiskers also exhibits substantially improved electromagnetic shielding properties. The hybrid ceramics with 10 wt. % silicon carbide whiskers and a 1 mm thick 1.5 wt. % carbon nanotube layer, show higher than 50% absorption of electromagnetic radiation.

Abstract:

In recent years, composite materials have dominated the electronics industries and other manufacturing industries. Hence, composite materials like aluminium silicon carbide (AlSiC), has been employed to produce heat sinks, which are used mainly to manage heat in electronic devices. However, thermal fatigue of such composite material is a major challenge in maintaining reliability of the device. This paper investigates the thermomechanical effect of AlSiC composite materials. Finite element method (FEM) was used in the analyses of the composite materials based on the particulate inclusions between 10 – 50% compositions. The thermal profile (-40oC to 85oC) employed in this study is used commercially for consumer products. The fatigue life of the composite material which is based on the stresses and strains parameters were obtained and evaluated. The results from this investigation suggests that the deformations, strains, and stresses reduced with increase in the percentage of particulate inclusions. Also, the fatigue life of the composite material showed that the reliability of the material is increased with higher inclusions. This investigation demonstrated that 50% particulate inclusions has a better number of cycles to fatigue failure (5.09E+04) when compare to other inclusions. While 10% inclusions has the least fatigue life (4.39E+04) based on this investigation. Keywords: composite material; temperature profile; silicon carbide; thermal fatigue

Abstract:

In this paper, the influence of a laser surface treatment on the structure and properties of aluminium alloy has been determined. The aim of this work was to improve the tribological properties of the surface layer of the EN AC-51100 aluminium alloy by simultaneously melting and feeding silicon carbide particles into the molten pool. The silicon carbide powder was introduced into the liquid metal using a gravity feeder within a constant feed rate of 1 g/min. A high power diode laser (HPDL) was used for remelting. Laser beam energies used in experiments were 1.8 kW, 2.0 kW and 2.2 kW, combined with the constant velocity of 50 mm/min. As a result of the laser treatment on the aluminium alloy, a composite layer with greater hardness and wear resistance compared to the based material was obtained.
