Present paper reports an overview on the processing, corrosion behavior and applications of various metal matrix composites with a special focus on iron based metal matrix nanocomposites. As iron has a much higher melting temperature compared to aluminum, copper and magnesium therefore it is synthesized using powder metallurgy technique. P/M technique is widely used because it provides microstr...

The automobile industry uses magnesium for load-bearing components due to its low density, durability, and ductility. This study investigated a nanocomposite containing Nb2O5 (3 6 wt%) nanoparticles as reinforcement with AZ31 alloy made by stir casting. A severe plastic deformation was conducted on the cast samples via equal-channel angular pressing (ECAP) after homogenization at 410 °C 24 h ag...

Wear experiments have shown that when the applied normal stress exceeds a critical value, a transition occurs from the regime of mild wear to that of adhesive wear. As a result, the wear rate of particle-reinforced aluminium composites increases by a hundred-fold. Based on dislocation and delamination theories, a criterion is proposed for determining the critical transition load, and a quantita...

Multiwalled boron nitride nanotubes (BNNTs) have very attractive mechanical and thermal properties, e.g., elasticity, tensile strength, and high resistance to oxidation, and may be considered as ideal reinforcing agents in lightweight metal matrix composites. Herein, for the first time, Al-BNNT ribbons with various BNNT contents (up to 3 wt.%) were fabricated via melt spinning in an argon atmos...

Due to its exceptional mechanical characteristics combined with lightweight and fuel-efficient materials, metal matrix composites (MMCs) have largely been developed for the automotive aerospace industries. In this paper, an attempt was made investigate dry sliding wear behavior of aluminium-based hybrid MMC's through experimental approach. The experiments were performed three types filler mater...

In this present study, A356.2 Al/Rice hush ash (RHA) metal matrix composites (MMCs) were fabricated by vortex method. Different weight fractions of reinforcement were used to fabricate the composites. Scanning electron microscope equipped with energy dispersive Xray analyzer is used for micro structural characterization. The properties like density, hardness, and ultimate tensile strength were ...

Metal Matrix Composites (MMCs) are present engineering materials which have more advantages when compare to conventional materials. Magnesium based MMCs among the MMCs have become an important research subject because of their low density and high strength/weight ratio in recent years. The aim of this study is to find out the most influence factors of the electro-discharge machining (EDM) proce...

Electrical discharge machining (EDM) is the process of machining electrically conductive materials by using precisely controlled sparks that occur between an electrode and a work piece in the presence of a dielectric fluid. Aluminium metal matrix composites (AMMCs) refer to the class of light weight high performance aluminum ceramic material systems. The reinforcement in AMMCs could be in the f...
