Study on Mechanical Properties and Microstructure of Aluminium Alloy 63401 Reinforced with Alumina Powder

Objectives: This paper includes the study of mechanical properties and microstructure characterization of aluminium alloy 63401 reinforced with alumina powder of different mesh size and different weight percentage. Methods: Fabrication of composite material is done by stir casting process because it is the cheapest way to fabricate mass samples. Different grain size of (149μm, 74μm, 37μm) and different weight percentage of (3%, 6%, 9%) have been used in this experiment. Findings: The tensile strength, impact strength and hardness of the composite material produced by reinforcing alumina powder increases with increase in the percentage of alumina powder and also vary with particle size of alumina powder. Applications: This type of composite material can be used in aerospace and automobile sectors.
