CHARACTERIZATION OF PARTICULATEREINFORCED ALUMINIUM 7075 / TIB2 COMPOSITES

Aluminum-based metal matrix composite (MMC) materials are used in the design of ground transportation vehicles and aircraft structures due to its light weight and high strength to weight ratio. Compared with conventional, unreinforced alloys, composite materials usually exhibit higher strength, both at ambient and elevated temperatures, as well as good fatigue strength and wear resistance. Stir casting process is one of the most effective methods for manufacturing Metal matrix composites (MMCs) due to its high volume reinforcement and fairly uniform distribution. This work deals with the production of Aluminium 7075 alloy reinforced with TiB2 particle. The composites were fabricated by three varying the volume % of Titanium diboride (TiB2) particles. The mechanical properties and microstructure analysis are identified from the experimental results and the ability of the manufactured aluminium matrix composite from the different reinforcements.
