“…Specimens were prepared as per the international standards and tensile, hardness and impact tests are performed.It was found that hardness increases with increase in wt% of SiC reinforcement. Hardness and tensile strength of 6wt% SiC composite is found to be higher than 2 & 4 wt% of SiC [3]. The tensile and fracture behaviour of as cast and age hardened aluminum (6063), silicon carbide particulate composites produced, using borax additive and a twostep stir casting method.…”

The current paper deals about the fabrication of composite material is to combine the desirable attributes of metals and ceramics. Aluminium 6063 used as a base material in combination with the Silicon carbide ,Boron carbide and fly-ash were used as reinforcement material. Our intention is to increased or enhanced properties of pure Aluminium 6063 by addition of Silicon Carbide ,Boron Carbide and fly-ash. The process of fabrication composite material is prepared by using stir casting method. In this paper, addition of Silicon Carbide 1% , Boron Carbide 1% and fly-ash1% with aluminium increasing percentage ratio the mechanical properties of composite material is enhanced, so it is clear that the effect of Silicon Carbide , Boron Carbide and fly-ash were helpful to increasing properties of pure Aluminium by addition. The influence of reinforced ratio of silicon carbide, Boron carbide and fly-ash particles on mechanical behavior was examined. The effect of different weight percentage of silicon carbide, Boron carbide and fly-ash in composite on tensile strength, hardness, microstructure was studied. It was observed that the hardness & tensile strength of the composites increased with increasing reinforcement elements addition in it. The distribution of silicon carbide, Boron carbide and fly-ash particles was uniform in aluminum.

Various metal matrix composites (MMCs) are widely used in the automotive, aerospace and electrical industries due to their capability and flexibility in improving the mechanical, thermal and electrical properties of a component. However, current manufacturing technologies may suffer from insufficient process stability, reliability and inadequate economic efficiency and may not be able to satisfy the increasing demands placed on MMCs. So CNT based Aluminium based metal matrix composites (MMCs) has been a better choice for the industrial applications due to their Inherent properties like ductile, highly conductive, lightweight and have a high strength to weight ratio. In this study, Multiwall carbon nanotube(MWCNT) which is emerged as an excellent reinforcement material and 2024 aluminium alloy being a matrix material were selected for the development of MMC‟s. Stir casting process being a low cost casting technology which has potential to produce MMCs having agility to large scale production with great manufacturing flexibility, quality and high efficiency. In this work, The experimental investigation of CNT reinforced 2024 Aluminium MMCs under Stir casting technique were explored. Casted samples were prepared with different wt. % of reinforcements(i.e. 0.5 %, 1.0%, 1.5% & 2 % CNT‟s with 40micron nickel coating on the surface using electro-less plating process) and compared with unreinforced aluminium specimens for the investigation of Wear properties has been evaluated as per ASTM standard.
