摘要

Aluminum metal matrix composites are critical materials in high-demand sectors due to their lightweight and exceptional stiffness. However, their application in high-stress environments is limited by insufficient strength and durability, necessitating innovations to improve their mechanical performance. This research focuses on strengthening Al6061 alloy by integrating zirconium (Zr) and titanium carbide (TiC) as reinforcement agents. Using the stir-casting process, various composite samples were developed, ranging from pure Al6061 alloy to blends containing different percentages of Zr and TiC. This method was selected for its ability to ensure uniform distribution of reinforcement particles by optimizing stirring conditions such as speed, duration, and temperature. The study assessed mechanical properties such as tensile strength, elongation, hardness, and wear resistance. Among the samples, the composite with 0.5% Zr and 10% TiC exhibited remarkable improvements, achieving tensile strength of 175.41 MPa, elongation of 26.5%, hardness of 71.2 N/mm2, and wear resistance of 0.105 microns/m. These enhancements stem from the synergistic effects of TiC and Zr, which reinforce the alloy’s microstructure and improve its load-bearing capabilities. This investigation highlights the potential of tailored reinforcement strategies to significantly improve the mechanical behavior of aluminum alloys, paving the way for their application in environments requiring exceptional strength, wear resistance, and reliability.
