Semisolid Processing of Al/β-SiC Composites by Mechanical Stirring Casting and High Pressure Die Casting

Tribological behaviour of AA 5083/Micron and Nano SiC composites fabricated by ultrasonic assisted stir casting process

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...

Casting of SiC Reinforced Metal Matrix Composites

Composites based on two aluminium alloys (A536 and 6061) reinforced with 10% or 20% volume fraction of SiC particles were produced by gravity casting and a novel two-step mixing method was applied successfully to improve the wettability and distribution of the particles. The SiC particles were observed to be located predominantly in the interdendrit ic regions, and a thermal lag model is propos...

Comparative Analysis Of Aluminium Metal Matrix Composites Reinforced With TiC And TiB2 Using Stir Casting Process

Composite materials are playing major and vital role in various sectors especially in aeronautical, defence and automotive sectors. It is preferable because of obtaining unique characteristics such as high specific strength, high stiffness, high corrosion resistance and low density. In the present work deals with the influence of Titanium carbide and Titanium boride reinforcements in different ...

Improving of Microstructure and Mechanical Properties of Al-A356 Alloy with Compo-Casting Method

Aluminum/alumina composites are used in automotive and aerospace industries due to their low density and good mechanical strength. In this research, the effect of mechanical stirring of slurry in liquid-solid phase temperature and injection of alumina powder with inert gas (Ar) on microstructure and mechanical properties of Al-A356 alloy is investigated. In order to improve of the wettability a...
