Abstract

In this study, aluminum-based metal matrix composites (MMCs) were fabricated with varying compositions of SiC and TiO₂ reinforcements using the stir casting method. Three different compositions were examined: 98% Al6061 alloy, 1% SiC, and 1% TiO₂; 96% Al 6061 alloy, 2% SiC, and 2% TiO₂; and 94% Al alloy, 3% SiC, and 3% TiO₂. These MMCs were evaluated for their mechanical behavior and microstructure in terms of tensile, flexural, and impact strength. Scanning electron microscopy (SEM) analysis revealed a uniform distribution of reinforcements, while also indicating an uneven dispersion of SiC particles within the Al matrix. Tensile testing displayed an ultimate strength of 160.06 MPa, an elongation of 6.63%, and a hardness of 96.5 for the sample with the composition of 94% Al, 3% SiC, and 3% TiO₂. For the composition of 96% Al alloy, 2% SiC, and 2% TiO₂, the highest flexural strength of 6.57 kN, notable impact strength of 6 J, and a hardness value of 93.68 were achieved. Atomic force microscopy (AFM) was employed to analyze surface morphology. These results demonstrate the potential of these MMCs for practical applications due to their improved properties compared to commercially available composites. The study highlights the tailored mechanical attributes of metal matrix composites, showcasing their strength, stiffness, fatigue resistance, and corrosion resistance. Such systematic analyses aid in the development of more efficient and dependable structures for wind turbine applications.

用碳化硅和二氧化钛增强 Al-MMC 的综合研究：风力涡轮机应用的机械性能、SEM 分析和结构适用性方面的进展

摘要在这项研究中，采用搅拌铸造法制造了铝基金属基复合材料（MMC），其中添加了不同成分的 SiC 和 TiO2 增强材料。研究了三种不同的成分：98% Al6061 合金、1% SiC 和 1% TiO2；96% Al 6061 合金、2% SiC 和 2% TiO2；以及 94% Al 合金、3% SiC 和 3% TiO2。对这些 MMC 的机械性能和微观结构进行了拉伸、弯曲和冲击强度评估。扫描电子显微镜（SEM）分析表明，增强材料分布均匀，同时也表明碳化硅颗粒在铝基体中的分散不均匀。拉伸测试显示，成分为 94% Al、3% SiC 和 3% TiO2 的样品的极限强度为 160.06 兆帕、伸长率为 6.63%、硬度为 96.5。铝合金成分为 96%、SiC 成分为 2%、TiO2 成分为 2%的样品的抗弯强度最高，为 6.57 kN，冲击强度为 6 J，硬度值为 93.68。原子力显微镜（AFM）用于分析表面形态。这些结果表明，与市售复合材料相比，这些 MMC 具有更好的性能，因此具有实际应用的潜力。这项研究强调了金属基复合材料量身定制的机械属性，展示了它们的强度、刚度、抗疲劳性和耐腐蚀性。这种系统分析有助于为风力涡轮机应用开发更高效、更可靠的结构。
