Magnesium matrix composites are very attractive materials for various applications of aerospace, defence organizations and automotive industry due to their low density, good mechanical and physical properties. The improvement of specific strength, stiffness, damping behaviour, wear behaviour, creep and fatigue properties are significantly influenced by the addition of reinforcing elements into ...

Friction Stir Processing (FSP) is a recent outgrowth of the Friction Stir Welding (FSW) process and relies on solid-state deformation to modify the surface of the working surface/materials. Our work to date has shown to locally eliminate casting defects and refine the microstructure to improve their mechanical properties and enhance corrosion resistance. Such improvements have important implica...

Metal matrix composites (MMCs) are now gaining their usage in aerospace, automotive and biomedical industries because of their inherent properties like high strength to weight ratio, low wear rate etc. To machine these types of materials conventional machining methods are unsuitable because of high tool wear and tooling cost. Electro discharge Machining (EDM) is one of the important nontraditio...

Non homogeneous particle distribution is one of the greatest problems in casting Metal Matrix Composites (MMC's). To optimize some of the parameters for uniform particle distribution for batch compocasting the present simulation studies were conducted. The simulation involves visualisation experiments. In the visualisation experiments liquid and semi solid aluminium are replaced by other fluids...

This paper describes the fabrication and mechanical testing of Al-Mg-boron carbide particulate composites using stir casting technique. The size of the boron carbide particulates is ranging between 30 to 100 μm. The boron carbide contents are varied from 3 and 7% by weight and are dispersed in the alloy matrix. The mechanical properties of the castings, particularly their tensile properties and...

In the present study, an attempt has been made to investigate the influence of the forging parameters on cutting forces for different cutting speed, depth of cut, and feed rate during machining of Al 7075 alloy and Al 7075 alloy with short basalt fiber reinforced metal matrix composites. The experiments were conducted by using a lathe machine with tool dynamometer setup. KeywordForging effect, ...

luminium based composite are getting a vast scope nowadays because of its properties and availability. In the present work, fly ash and AL2O3 reinforced composite are prepared using stir casting technique for varying wt.% (fly ash 3% and AL2O3 3%, 6% & 9%). Hardness and tensile properties were determined, with the addition of reinforcement the properties are improved compared to the parent meta...

Metal Matrix composites (MMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence and other industries. MMCs are projected to significantly reduce the overall weight of the vehicle and aircraft while maintaining satisfactory structural strength. Micron and Nano-sized ceramic particle reinforced aluminum matrix composites fabricat...
