“…They observed that the mechanical properties were increases as the percentage contribution of SiC particles were increases. Milos et al [13] worked on the development of composite by Al5083 alloy reinforced with Al2O3 and graphite. The weight % and size of the reinforced particles was chosen as a variable to study the effect on mechanical properties.…”

In the present investigation, an attempt was made to utilize RHA in the development of aluminium based composite material. AA6061 alloy was melted in muffle furnace. Preheated RHA and SiC were added in the aluminium alloy. Composite material was fabricated by stir casting technique. Microstructure image showed proper wettability of reinforcement material with aluminium alloy matrix. Uniform distribution was observed of reinforcement particles in aluminium alloy. It has been observed that by using the RHA and SiC simultaneously in aluminium alloy, mechanical properties were improved significantly. However; toughness and ductility were reduced. Heat treatment of composite material was also carried out to observe the enhancement of mechanical property. Results showed that after the heat treatment process, mechanical properties were further improved.

“…A proper selection of matrix & reinforcement and shape of the reinforcement is highly desirable for property improvement of the composite [7][8][9]. In recent years, aluminium and its alloys are most widely used non-ferrous metals and getting more popularity due to its high strength to weight ratio, easy to fabricate, and low production cost [10,11,12]. Aluminum metal matrix composites (AMMCs) reinforced with ceramic particles are simple & easy to process and also have the potential to give tailored property combinations [13].…”

In recent years, aluminium and its hybrid composites receiving more attention due to its excellent property combinations like improved mechanical properties, better wear and high corrosion resistance, ease to process and probably reduced production cost etc.. Composite is made of two phases one is matrix and another one is reinforcement. The performance of composite highly depends on some key factors that decide overall performance and they are properties of constituent phases, reinforcement size, reinforcement distribution in the matrix and their interfacial interaction. Particle reinforced metal matrix composites (particulate metal matrix composites- PMMCs) are becoming more popular due to their low cost, easy to process and compatible to conventional processing techniques. Also they give isotropic properties. The most commonly used reinforcements are carbides, oxides and nitrides. A lot of research has taken place including carbide and oxide as a reinforcement particles for aluminum matrix composites (AMCs) and hybrid aluminium matrix composites (HAMCs) while there is a bit research lag in use of nitride as a reinforcement for development of AMCs and HAMCs. Recent competitive market demands the material having better combination of properties, cost effectiveness and eco-friendly nature. Present article focused on to study the microstructural features, physical properties, mechanical and tribological behavior of aluminium matrix composites when reinforced with silicon nitride particles (Si3N4). Potential area of applications has also been suggested on the basis of literature data. In this review a comprehensive study has done for current scientific development carried out in Al based Si3N4 composites as well as its future scope has also been discussed

“…Previous investigations where Al was reinforced by micro Al 2 O 3 with content ranging from 2050 wt-% showed a significant reduction in the Coefficient of Thermal Expansion (CTE) compared to unreinforced Al (Milos et al, 2011). Since the restriction effect of reinforcement particles causes CTE reduction, it is expected that using nanoparticles as reinforcements would even further reduce composite CTE.…”

Aluminum alloy is one of the materials found in many applications, especially for electrical conductor materials. AlZrCe alloy reinforced by Al 2 O 3 nanoparticles with Mg addition is proposed as one of the alternative materials to replace Aluminum Conductor Steel Reinforced (ACSR) as an aluminum conductor. Aluminum alloy Al-0.12%Zr-0.15%Ce as a master alloy was added with various weights of magnesium (Mg) from 2 to 5 wt% and was reinforced with 1.2% volume fraction of Al 2 O 3 nanoparticles with particle sizes less than 80 nm. The molten metal matrix was blended with the reinforcement by a stirrer with a rotational speed of 500 rpm at a temperature of 750 o C in an argon gas environment and casted by gravity casting. The objective of this research was to investigate the effect of magnesium on microstructural changes, electrical conductivity, and mechanical properties, such as tensile strength and hardness of the composites. The microstructure observation results showed that the greater the Mg content in composites up to 5%, the smaller the grain size of the composite matrix, wherein the grain size of the composite without Mg is 28 μm, while the grain size of the composite with Mg of 2%, 3% and 5% are 27 μm, 17 μm and 9 μm respectively. Similarly, tensile strength and hardness increased with increasing levels of Mg to 5% where the addition of 5% Mg, the tensile strength increased from 106 to 204 MPa and hardness increased from 30 to 68 BHN. In contrast, the electrical conductivity sharply decreased, due to the addition of Mg in the composite with a gradient of reduction, to 2.74% IACS (International Annealed Copper Standard) for every increasing 1% Mg. In which the electrical conductivity of the composite without Mg is 55.1% IACS and after adding 5 wt% Mg, it decreased to 41.3% IACS.
