This study was conducted to investigate the synthesis, characterization and mechanical properties of aluminium reinforced with ferrotitanium and silicon carbide via stir casting technique. Microstructures of as-cast samples were analysed using optical and scanning electron microscopes equipped with energy-dispersive X-ray spectroscopy. The mechanical properties in terms of hardness, tensile, tribological behaviour and fracture were assessed. Results showed that the homogeneous dispersion of reinforcement was within the metal matrix composite. Tribological study revealed a decrease in frictional coefficient of the composites with lowest frictional coefficient observed in composite with addition of silicon carbide as reinforcement. Morphology of fractured surface displayed a reduction in the size of dimples formed in reinforced aluminium composites when compared with larger dimple sizes observed in as-cast aluminium alloy.

通过搅拌铸造技术开发的新型 Al-(Mg-TiFe-SiC) 金属基复合材料的表征和机械响应

本研究旨在通过搅拌铸造技术研究钛铁和碳化硅增强铝的合成、表征和机械性能。使用配备能量色散 X 射线光谱仪的光学和扫描电子显微镜分析铸态样品的微观结构。评估了硬度、拉伸、摩擦学行为和断裂方面的机械性能。结果表明，增强体均匀分散在金属基复合材料内。摩擦学研究表明，在添加碳化硅作为增强材料的复合材料中，摩擦系数最低的复合材料的摩擦系数降低。
