Fabrication of Aluminium Metal Matrix Composites with Particulate Reinforcement: A Review

Abstract

This paper presents a summary of work reported on Aluminium metal matrix composites with particulate reinforcement. Aluminium metal matrix has growing demand in aircraft, automotive and other industries due to its light weight, high strength to weight ratio, corrosion resistance and workability. Particle reinforced aluminium matrix composites are preferable due to their reduced cost, uniform properties, and their ability to be like monolithic materials. Although numerous method are available to fabricate the particulate metal matrix composite, stir casting is the most preferable one due to its cost effectiveness and convenience. Present paper reviews the problems taken and results obtained by various authors who have contributed in the area of Aluminium metal matrix composites with particulate reinforcement through stir casting. The reported works reveal that decrease in particle size and increase in percentage addition of reinforcement increase hardness and tensile strength of the composite.
