“Investigation on Mechanical Behaviour of Aluminium Metal Matrix Al6061 Reinforced with Varying Wt. % Aluminium Oxide (Al2O3) And 5% Molybdenum Di-Sulphide (Mos2) Micron Particles”

Abstract

The study focused on the mechanical characteristics of hybrid metal matrix composites made of Al 6061 alloy reinforced with Molybdenum Di-sulphide (MoS₂), and Aluminium Oxide (Al₂O₃) in micron form. The composites were made by employing the stir casting technique to reinforce the Al6061 base metal with different weight fractions of aluminium oxide (Al₂O₃), ranging from 5 to 20%, while maintaining a constant weight of molybdenum disulphide (MoS₂) 5%. Samples were machined in accordance with ASTM standards E8 & E10 and put to the test under standard testing settings utilizing a universal testing machine and a Brinell hardness testing machine in order to assess the mechanical properties of the manufactured hybrid composite like Ultimate Tensile Strength and Brinells Hardness. The study findings may shed light on the possible usage of metal matrix hybrid composites in fields including aerospace, automotive,--etc. that call for great mechanical strength.
