The main objective of the current study was to create AA6082/ Al 2 O 3 /C/Si 3 N 4 Composite Material by the use of stir casting. The properties of the AA6082/ Al 2 O 3 /C/ Si 3 N 4 Composite Material shown a significant improvement, with a micro-hardness rise of 13.5% and a residual stress decrease of 60%. As the testing parameters were increased, the residual stress of the AA6082/ Al 2 O 3 /C/ Si 3 N 4 Composite Material rapidly decreased from -65MPa to – 15MPa. An electromagnetic stirrer was used in this study’s stir casting process to create the AA6082/ Al 2 O 3 /C/ Si 3 N 4 Composite Material. After using acetone to clean them, the AA6082 rods were divided into smaller pieces and heated to 850°C in an electric muffle furnace. The crucible was then used to melt the rods. The findings of the residual stress test showed a 60% decrease. The current discovery reported an increase in the hardness of the composite material AA6082/ Al 2 O 3 /C/ Si 3 N 4 Composite. Experimental research has demonstrated that the development of nitrides and oxides in the manufactured composite leads to a decrease in residual stress. As the testing parameters were increased, the micro-hardness of the AA6082/ Al 2 O 3 /C/ Si 3 N 4 Composite Material rapidly increased from 210 HV to 260 HV. The corrosion test results also revealed a notable mass loss of the AA6082/ Al 2 O 3 /C/ Si 3 N 4 Composite Material sample, with decreases of approximately 55.2% after 1.5 hours, 43.1% after 2.5 hours, and 32% after 3.5 hours of exposure. Experimental research has demonstrated that the development of nitrides and oxides in the manufactured composite leads to a decrease in mass loss. When the generated composite solidifies, the increased dislocation density causes a decrease in grain size, which may be the cause of the increase in micro-hardness.
