| Popis: | Nowadays, composites are profoundly thriving as the replacement of ferrous alloys. The Aluminum manifested into a great substitute due to its properties like lightweight, low density, high strength, and corrosion resistance. The process of fusing the non-ceramics reinforcement like Silicon carbide, Boron carbide, Aluminum oxide, Titanium diboride with a non-metal like Graphite, Molybdenum disulfide or with other non-ceramic to form a hybrid metal matrix composite. In the present paper, an investigation carried out on Aluminum 7075 material by the process of stir casting where the Silicon Carbide (SiC) with three different weight % (i.e., 3%, 6%, 9%) and Molybdenum Disulphide (MoS2) with 1% constant weight % added to the base material. The tensile test and hardness test were then done on a UTM and Rockwell Hardness testing machine, respectively, for all three prepared materials. As the percentage of SiC increases in the material, the hardness value and tensile strength are increasing. The Al7075 + 9%SiC + 1%MoS2 is the highest of all. |
