In the present investigation research work is based on development of Al 6063 base hybrid metal matrix composite reinforced with 10 weight percentage of Aluminium Oxide (Al2O3), and varying weight percentage of Molybdenum disulphide (i.e. 3%, 5%, 7% & 9%). The composite was prepared by using stir casting technique. The density of Al 6063/ MoS2/ Al2O3 were increasing when reinforcement of MoS2 increases from 3% to 9%. The Ultimate Tensile Strength decreasing due to the additions of 3% to 9% of MoS2 and also reinforced with alumina (Al2O3) into the base matrix. It was seen that while the Al 6063 alloys shows the pre- dominantly ductile fracture (base matrix). The composite specimens (with a MoS2 addition) show an increase in the mixed mode (ductile and brittle regions). Investigation also predicts that hardness increases due to varying addition of MoS2. Micrographs of the composite specimen are taken for the study of particular or overall behavior of the material.
