This study looks at how stirring speed, particle size, and Si₃N₄ content affect the strength, hardening, and corrosion properties of Al1050, using MINITAB 16 software to analyze the results. The composite material was made by mixing different amounts of Si₃N₄ (2, 4, and 6 wt%), using Si₃N₄ particles of sizes 32, 44, and 53 micrometers, and stirring at different speeds of 300, 600, and 900 revolutions per minute. The stir casting technology was employed to manufacture a composite material. The microscopic structure was analyzed utilizing SEM microscopy. The results for the best tensile strength and hardening values of 202 MPa and 66 kg/mm² were reached with the settings of X1 = 900 rpm, X2 = 44 μm, and X3 = 6 wt%. The optimum tensile strength was determined to be 212.55 MPa, achieved with parameters X1 = 900 rpm, X2 = 32µm, and X3 = 6 wt%, as indicated by the program. This result closely aligns with the practical test outcome, which recorded a tensile strength of 209.7 MPa, demonstrating a strong correlation with the program's findings. Both tensile strength and hardness improve with increasing stirring speed and reinforcing percentage, indicating their substantial influence. As particle size increases, tensile strength and hardness first fall and then slightly rise. The stirring speed has the most significant impact, whereas the particle size has the least influence on the mechanical properties. Regarding the chemical characteristics, corrosion tests measuring weight loss have been conducted on MMC and related base alloys utilizing exposure durations (5-30 min), temperatures (25°C), and corrosive fluids of 3.5% NaCl, where the composites are less prone than the matrix to corrosion and pitting. It was discovered that the weight loss of base alloys and MMC increased with contact time. Additionally, it was discovered that both the base alloy and the composite materials corrode more when the temperature rises. It was observed that the corrosion rate decreased with increasing Si₃N₄ reinforcement.
